When Radiation Monitoring Badges Are Required (top)

Under Princeton University requirements, you must wear radiation monitoring badges if:

• You operate x-ray machines (including x-ray diffraction equipment and the Molecular Biology Department Faxitron cabinet x-ray system)
  
• You are a Declared Pregnant Worker working in a lab where x-ray and gamma emitters or energetic beta emitters are used
  
• If you use radioactive materials under the following conditions:

Examples of how the monitoring badge requirements are applied:

• If your lab receives a 5 mCi vial of P-32 and you briefly handle the 5 mCi vial to withdraw an aliquot of 100 uCi, you are not required to wear monitoring badges.
  
• If you order 5 mCi of P-32 and you perform a synthesis using the entire 5 mCi, you are required to wear monitoring badges.

Optional Monitoring (top)

If you work in a laboratory in which gamma emitters or energetic beta emitters are used, you may request radiation monitoring badge service, even if you do not meet the criteria for required monitoring.

Monitoring is not generally provided for persons working in laboratories in which only alpha emitters or low energy beta emitters (< 250 keV) are used, since our radiation monitoring badges cannot detect these radiations.

How to Request or Cancel Monitoring Badge Service (top)

To request radiation-monitoring services, to cancel monitoring badges, or to request a replacement for a lost or damaged badge, you may contact EHS directly by completing the Radiation Monitoring Badge Service Request Form. You may also ask the PI in charge of your lab or lab manager to request monitoring services. Please provide EHS with the following information: name, department, name of the laboratory in which the primary radiation exposure occurs, purpose of request (i.e., new service, replacement for a lost/damaged badge, etc.), the source of radiation exposure (radioisotopes, x-ray machines, etc.), length of time for which monitoring service is needed, and the urgency of the request.
