Florida Radiation Safety Rules for Imaging Centers

Imaging centers operating in Florida must comply with Chapter 64E-5 of the Florida Administrative Code, the state's Control of Radiation Hazard Regulations, administered by the Florida Department of Health (FDOH) through its Bureau of Radiation Control. Diagnostic X-ray machines — CT, radiography, fluoroscopy, mammography, and dental units — are registered with FDOH as radiation-producing equipment, while radioactive material used in nuclear medicine and PET is licensed under Florida's NRC Agreement State program. These are two distinct compliance pathways, and conflating them is one of the most common ways facilities get tripped up.¹²⁶

This guide walks through the core obligations a Florida imaging facility faces — equipment registration, personnel qualifications, qualified-physicist surveys, mammography under MQSA, radioactive-material licensing, personnel monitoring, and inspection readiness — and how each obligation maps to the specific governing rule. DRPS provides these services across Florida and also serves Maryland, Virginia, Washington DC, California, and Nevada.

Introduction

Florida's radiation safety framework layers a state machine-registration program over the federal standards that govern radioactive material and mammography. Chapter 64E-5 is the spine of that framework: it sets registration, operating, survey, shielding, and recordkeeping requirements for every facility that produces ionizing radiation or possesses licensed sources, regardless of practice setting.¹ Meeting it is essential for legal operation, patient and staff safety, and for avoiding citations during the inspections FDOH conducts.

Because Florida is an NRC Agreement State, the state — not the U.S. Nuclear Regulatory Commission — issues and enforces radioactive-material licenses, while still adhering to the radiation-protection limits that mirror 10 CFR Part 20.²³ At the same time, mammography carries a federal overlay under the Mammography Quality Standards Act (MQSA), implemented through 21 CFR Part 900, that applies in every state.⁷ Understanding which authority owns which piece of your program is the first step to staying compliant.

Topic Explanation: Machine Registration vs. Material Licensing

The single most important distinction in Florida radiation safety is between radiation-producing machines, which are registered, and radioactive material, which is licensed. These categories follow separate legal pathways, separate fees, separate inspection cycles, and separate parts of the rule.

• "Radiation-producing equipment" means machines that generate ionizing radiation electrically — X-ray tubes in CT scanners, radiographic and fluoroscopic systems, mammography units, bone densitometers, and dental units. These are registered with FDOH under Chapter 64E-5.¹
• "Radioactive material" means licensed sealed sources and radiopharmaceuticals, such as F-18 FDG for PET/CT, Tc-99m generators for general nuclear medicine, and therapy isotopes such as Lu-177. These are licensed under Florida's Agreement State program, which mirrors the federal medical-use framework in 10 CFR Part 35.²⁴

A facility that runs both a CT scanner and a PET service has two compliance obligations: a machine registration for the CT and a radioactive-material license for the PET radiopharmaceuticals. The qualified medical physicist's scope likewise splits — equipment performance evaluations on the machine side, and radiation safety program support, shielding, and survey work on the material side. For a step-by-step walkthrough of the licensing pathway, see the NRC Radioactive Material License Guide, and for the isotopes that drive nuclear-medicine licensing, see Understanding Common Isotopes in PET & Radiopharmaceutical Therapy.

Key terms

• FDOH Bureau of Radiation Control — the administering authority for Chapter 64E-5 and the Agreement State program.¹²
• Qualified medical physicist (QMP) — a professional who is board-certified (for example, by the American Board of Radiology) and meets state requirements to evaluate a given modality.⁸
• Equipment performance evaluation (EPE) — the periodic physics survey of a radiation-producing machine that confirms output, dose, image quality, and safety performance.
• Radiation Safety Officer (RSO) — the individual named on a radioactive-material license who is responsible for the day-to-day radiation safety program.⁴
• ALARA — keeping exposures As Low As Reasonably Achievable below the regulatory limits, not merely under the ceiling.

Florida Department of Health Regulations

The Florida Department of Health, through its Bureau of Radiation Control, regulates radiation-producing equipment and radioactive materials under Chapter 64E-5 of the Florida Administrative Code. The rule applies to all facilities using X-ray equipment, CT scanners, fluoroscopy systems, mammography units, dental units, and other radiation-producing devices, as well as facilities possessing licensed radioactive material.¹

Equipment Registration Requirements

All radiation-producing equipment must be registered with the Florida Department of Health before it is placed into clinical use. Registration requirements include:

• Initial registration: New equipment must be registered with FDOH following installation.
• Renewal: Equipment registrations must be renewed on FDOH's schedule (annual renewal and fee under the registration rule).
• Equipment changes: Modifications, additions, or relocations require an updated registration.
• Decommissioning: Proper notification is required when equipment is removed from service.

Registration is administrative, but it is the gate to everything else. An unregistered machine cannot be legally operated, and an expired registration is among the most frequent citations FDOH issues.

Personnel Qualifications

Florida regulations specify who may operate and oversee radiation-producing equipment. Core personnel requirements include:

• Radiologic technologists: Must hold valid Florida licensure or recognized ARRT certification appropriate to the modality.
• Medical physicists: Must be board-certified and meet state qualification requirements to perform equipment evaluations.⁸
• Radiation Safety Officers (RSOs): Required for facilities that use radioactive materials, with responsibilities defined under the facility's radioactive materials license and the medical-use framework of 10 CFR Part 35.⁴

Key Technical Principles

Florida's radiation safety framework rests on three pillars: registration of equipment, qualification of personnel, and independent verification of performance and shielding by a qualified medical physicist. Underpinning all three are the dose limits Florida adopts through its Agreement State program, which mirror 10 CFR Part 20.

Dose limits Florida adopts

As an Agreement State, Florida adopts radiation-protection limits equivalent to the federal standards in 10 CFR Part 20:³

• Occupational total effective dose equivalent (TEDE): 5 rem (0.05 Sv) per year (10 CFR 20.1201).³
• Lens of the eye: 15 rem (0.15 Sv) per year; skin and extremities: 50 rem (0.5 Sv) per year (10 CFR 20.1201).³
• Public dose: 0.1 rem (1 mSv) per year, and 0.002 rem (0.02 mSv) in any one hour (10 CFR 20.1301).³
• Declared pregnant worker: 0.5 rem (5 mSv) over the gestation period (10 CFR 20.1208).³

ALARA means all programs are expected to keep exposures well below these ceilings, not just under them.

Reference table: requirement → governing rule → obligation

The table below crosswalks each major requirement area to its governing Florida rule (or the federal program where one applies) and the typical frequency or obligation. Section numbers reflect the current 64E-5 Part V structure; always confirm against the rule text in effect, because Florida periodically renumbers and amends these provisions.

These principles drive the specific medical physics, shielding, and quality-assurance requirements that follow.

Worked example: when is personnel monitoring required?

Florida, through its Part 20–equivalent program, requires individual monitoring when a worker is likely to receive more than 10% of an applicable dose limit (10 CFR 20.1502).³ For whole-body TEDE, 10% of the 5 rem annual limit is:

$$D_{\text{trigger}}=0.10\times 5\text{rem}=0.5\text{rem}=5\text{mSv per year}$$

A nuclear-medicine technologist handling Tc-99m and F-18 doses daily will typically exceed this trigger and must be issued a dosimeter; a front-desk staff member in an uncontrolled office area generally will not. The same 10% rule applies separately to the lens of the eye (10% of 15 rem = 1.5 rem) and to skin/extremities (10% of 50 rem = 5 rem), which is why interventional and hot-lab staff are often issued ring (extremity) badges in addition to a whole-body badge.³ For a deeper treatment of how monitoring programs are designed and read, see Occupational Exposure Monitoring Programs.

Worked example: an ALARA shielding design goal

Florida shielding designs follow recognized radiation-protection guidance such as NCRP Report No. 147, which expresses barriers as weekly design goals rather than annual limits directly.⁵ A common uncontrolled-area design objective is 0.02 mGy per week, which corresponds to roughly 1 mGy per year over a 50-week working year:

$$0.02\frac{\text{mGy}}{\text{week}}\times 50\text{weeks}\approx 1\text{mGy/yr}$$

For controlled areas the corresponding objective is 0.1 mGy per week (≈ 5 mGy/yr).⁵ These design goals are deliberately more restrictive than the absolute occupational limit so that the barrier supports sustained occupancy and ALARA. For the underlying methodology — attenuation, half-value layers, and barrier design — see Lead Shielding Design Principles in Diagnostic Imaging and Nuclear Medicine.

Medical Physics Requirements

Florida requires medical physics oversight of imaging facilities, anchored by periodic equipment performance evaluations performed by a qualified, board-certified medical physicist. Key requirements include performance testing, shielding verification, and a documented quality-assurance program.¹⁸

Equipment Performance Evaluations (EPEs)

Periodic physics evaluations — generally annual — are required for radiation-producing equipment and apply to systems including:

• CT scanners
• Fluoroscopy systems
• Mammography units
• General radiography systems
• Bone densitometry systems

EPEs must be performed by qualified medical physicists and typically include:

• Equipment performance testing
• Radiation dose measurements
• Safety interlock verification
• Image quality assessment
• Compliance documentation

For CT specifically, dose evaluation centers on metrics such as CTDIvol and DLP; for a deeper treatment of those metrics see Getting to the Core: Understanding CTDIvol and DLP in CT Dose Optimization. Mammography units carry an additional federal layer of oversight under MQSA, discussed in detail below.

Mammography and MQSA

Mammography is the one diagnostic modality where a federal program runs alongside Florida's state rules: every mammography unit in the country must comply with the Mammography Quality Standards Act (MQSA), implemented through 21 CFR Part 900.⁷ Under MQSA, a facility must be accredited by an FDA-approved accreditation body, certified by the FDA (or an FDA-approved state certifying agency), and inspected annually by an FDA-certified inspector.⁷

MQSA also mandates an annual survey by a qualified medical physicist that is independent of, and in addition to, any state EPE requirement.⁷ That survey evaluates parameters such as average glandular dose, image quality (including phantom scoring), automatic exposure control performance, collimation, and — for digital systems — detector and display performance. A missed or late MQSA physicist survey can place a facility out of compliance and jeopardize its certification and its ability to bill, so mammography surveys should never be allowed to lapse.

Shielding Requirements

Florida requires adequate radiation shielding for imaging facilities, designed and verified by a qualified medical physicist. Shielding design must:

• Follow recognized radiation-protection guidance, including NCRP Report No. 147 for diagnostic X-ray and CT shielding and NCRP Report No. 151 for megavoltage installations where applicable.⁵⁹
• Be designed or certified by a qualified medical physicist.
• Include post-construction verification surveys.
• Provide adequate protection for staff, patients, and adjacent public areas.

For PET/CT and nuclear-medicine suites, shielding must also address 511 keV annihilation photons and distributed patient sources — see our PET/CT Shielding Calculations Guide.

Quality Assurance Programs

Facilities must implement a documented quality-assurance (QA) program that demonstrates ongoing performance, not just point-in-time compliance. A QA program generally includes:

• Regular equipment testing
• Image quality monitoring
• Dose tracking and optimization
• Documentation and recordkeeping

For diagnostic interpretation, display performance is part of the chain — see Evaluating the SMPTE Pattern: Ensuring Monitor Performance for Accurate CT Interpretation.

Radioactive Materials Licensing

Facilities using radioactive materials — such as PET/CT and nuclear medicine — must hold an appropriate radioactive materials license. Because Florida is an NRC Agreement State, that license is issued and enforced by the State of Florida rather than directly by the U.S. Nuclear Regulatory Commission.²

• State license (Florida): Florida is an Agreement State, so radioactive materials are licensed by the State of Florida under an NRC-equivalent program.²
• NRC license: Required only for facilities located in non-Agreement States; the federal medical-use framework is codified in 10 CFR Part 35.⁴ (Note: among the regions DRPS serves, Washington DC is regulated directly by the NRC, while Florida, Maryland, Virginia, California, and Nevada are Agreement States.)
• License management: Ongoing compliance with license conditions, RSO duties, dosimetry, surveys, and reporting requirements is mandatory throughout the license term.⁴

For a step-by-step walkthrough of the licensing pathway, see the NRC Radioactive Material License Guide.

Clinical Impact

Compliance is not just paperwork — the same requirements that satisfy 64E-5 also protect patients and staff and keep imaging quantitatively reliable. Periodic physics evaluations catch dose drift and image-quality degradation before they affect diagnosis; verified shielding limits occupational and public exposure; and proper personnel qualification ensures studies are acquired and interpreted competently.¹⁸

For an imaging center, lapses translate directly into operational risk: a missed mammography survey can jeopardize MQSA certification and the ability to bill, an unregistered CT scanner can halt scanning, and an inadequate radiation safety program can trigger enforcement that suspends radioactive materials use. Treating compliance as part of clinical quality — rather than a separate administrative chore — keeps the facility both safe and open.

Inspection Requirements

Florida imaging facilities are subject to routine and unannounced inspections by FDOH.¹ Inspectors typically evaluate:

• Equipment registration compliance
• Personnel qualifications and licensure
• Radiation safety program implementation
• Personnel monitoring (dosimetry) records
• Documentation completeness
• Overall facility compliance with 64E-5

Mammography facilities additionally undergo the separate, federally mandated annual MQSA inspection conducted by an FDA-certified inspector.⁷

Common Compliance Issues

The most frequent violations found during Florida inspections are administrative lapses that are entirely preventable. Common findings include:

• Unregistered equipment
• Expired equipment registrations
• Missing or incomplete physics evaluations
• Overdue MQSA mammography surveys
• Inadequate radiation safety programs
• Insufficient documentation
• Unqualified or unlicensed personnel

For a broader, modality-agnostic look at the same patterns, see Common Radiation Safety Violations and How to Avoid Them.

Practical Tips for Compliance

Most Florida citations are avoidable with a few disciplined habits. To stay ahead of 64E-5 requirements:

1. Maintain current registrations — Keep every machine registered and track renewal dates so nothing lapses. Treat the dental and bone-density units with the same diligence as the CT — they are registrable machines too.
2. Schedule annual physics evaluations — Book EPEs (and MQSA mammography surveys) well in advance to avoid gaps in coverage.
3. Separate your two programs deliberately — Keep machine-registration records and radioactive-material license records as distinct, clearly owned files; they are inspected by different processes.
4. Document everything — Maintain complete records of physics evaluations, training, surveys, dosimetry, and corrective actions, ready to produce on inspection.
5. Right-size your dosimetry — Issue badges (including extremity badges in the hot lab) wherever the 10%-of-limit trigger is plausible, and review dose reports promptly.
6. Stay current — Monitor regulatory updates and changes to Florida and federal requirements.
7. Work with qualified physicists — Ensure all physics services are provided by board-certified, state-qualified medical physicists.

Regulatory Considerations

Florida imaging centers operate under a layered regulatory structure: state machine rules under 64E-5, the Agreement State framework for radioactive material, and modality-specific federal programs. Key references include:

• Florida Administrative Code Chapter 64E-5 — primary state rule (Control of Radiation Hazard Regulations) for radiation-producing equipment and radioactive materials.¹
• Florida Department of Health, Bureau of Radiation Control — the administering authority.¹
• NRC Agreement State Program — the basis for Florida-issued radioactive materials licenses.²
• 10 CFR Part 20 — radiation protection standards (dose limits, ALARA) that Florida's program mirrors.³
• 10 CFR Part 35 — medical use of byproduct material (federal framework mirrored by Florida).⁴
• MQSA / 21 CFR Part 900 — federal mammography quality, accreditation, certification, and physicist-survey requirements.⁷
• OSHA 29 CFR 1910.1096 — federal occupational ionizing-radiation standard applicable to the workplace.¹⁰
• NCRP Reports No. 147 and No. 151 — structural shielding design guidance.⁵⁹

Facilities pursuing ACR accreditation should align their physics program accordingly; see ACR Accreditation Physics Requirements.
