After radiopharmaceutical treatment, which actions are prohibited?

• A. Enter Radiological Zones
• B. Be Assigned Work
• C. Participate In The Dosimetry Program
• D. All Of The Above

Answer: (D)

After radiopharmaceutical treatment, you can still be radioactive for a period, so safety rules restrict several activities to protect yourself and others. Entering radiological zones is not allowed because you could spread contamination or receive more exposure, and these zones are controlled for safety. Being assigned work is restricted for the same reason—tasks that involve handling radioactive materials or operating related procedures could increase exposure to you or to coworkers. Participating in the dosimetry program is also restricted during the treatment period because your exposure status is still evolving and needs special management; normal dosimetry processes aren’t appropriate until you’re cleared. For these reasons, all of the listed actions are prohibited.
