Which regulation is cited as an ionizing radiation regulation in this material?

• A. 10 CFR 20
• B. AFMAN 48-148
• C. 21 CFR Part 11
• D. OSHA 29 CFR 1910.120

Answer: (A)

Ionizing radiation protection is governed by the Nuclear Regulatory Commission’s standards, codified as 10 CFR 20. This regulation lays out the requirements for protecting workers and the public from ionizing radiation, including exposure limits, ALARA principles, area monitoring, instrumentation, licensing, training, and recordkeeping. It provides the authoritative framework most often cited for ionizing radiation regulation in materials like this. The other options address different areas—one pertains to FDA electronic records and signatures, another to general occupational safety and hazardous waste-related rules, and a military manual that isn’t the statutory ionizing-radiation regulatory framework.
