Workers who intend to handle radioactive material (RAM), document RAM inventory, or perform RAM contamination surveys are required to enroll and complete the Radioactive Material Protection Course (RMPC).

The Approval Holder (AH) or Approval Safety Coordinator (ASC) must initiate the process by emailing with the following information:

  • Worker’s legal name
  • Official work email address
  • Approval Name and Number

The worker, AH and ASC will be notified of their status throughout the process.

Research Laboratory & Safety Services provides pregnancy counseling for radiation workers. This is a voluntary program available to all University of Arizona personnel.

Counseling is provided for radiation workers who are pregnant, suspect they may be pregnant, or who are planning a pregnancy. The counseling appointment will include a review of the work situation, an evaluation of monitoring requirements, and a discussion of the risks of radiation exposure during pregnancy. Formal declaration of one's pregnancy is voluntary and may be made following counseling.

Contact Research Laboratory & Safety Services at (520) 626-6850 to schedule an appointment.

Radiation Dosimetry

Research Laboratory & Safety Services (RLSS) evaluates individuals working with radiation to determine if radiation monitoring is required. This determination is done when an individual responds to an online invitation from RLSS.

Radiation dosimetry for wet chemistry applications of radioactive materials may require a bioassay either in vitro or in vivo analysis. RLSS offers the following bioassays:

  • Urine bioassay
  • Thyroid bioassay

There is a $25.00 fee assessed when dosimeters are late or missing according to the Unreturned Dosimeter Policy.

Dosimeters are worn only at the facility or department for which they were issued. They are not to be worn at secondary locations of employment. Request a dosimeter for each place of employment.

Contact Research Laboratory & Safety Services at (520) 626-6850 with questions or concerns.
