No, I have had no occupational exposure to radiation this calendar year. Yes, I have had occupational exposure to radiation this calendar year. I understand the presence of these hazards and will employ safe work habits minimizing this hazard to myself, coworkers, the general public, and the environment. Section 5 Certification I certify that the above information is correct to the best of my knowledge. This information is used for your permanent dosimetry records.
External dosimetry is inefficient for monitoring laboratory personnel.
No external monitoring is required for personnel using only radionuclides that produce low-energy radiations. External monitoring is effective for high-activity protocols only. If you are using less than 10 mCi per protocol, personnel monitoring is generally not needed. Laboratories utilizing less than 5 mCi are not required to use personnel monitoring. Clinics or laboratories performing x-ray fluoroscopy must wear a collar film badge and protective lead apron.
