Radiation Safety Guide

Radiation Protection Services (RPS) has the responsibility to implement the radiation safety program at Stony Brook University. The complete rules and regulations for the safe use of radioactive materials can be found in the University Radiation Protection Committee (URPC) Policies and Procedures booklet, which is available in each authorized radioactive materials laboratory. This booklet is provided to aid you in recognizing your responsibility for radiation safety. While it gives an overview of basic radiation safety procedures, it is the responsibility of each radiation worker to be thoroughly familiar with all applicable sections of the Radioactive Materials Safety Manual.

Radioactive Waste Disposal

Current instructions for disposal are provided on each of the types of waste containers supplied on request by the RPS. These instructions must be followed carefully and pertain to the most up-to-date information as supplied to RPS from the waste burial sites. Each deposit in a container must be logged on the container's contents sheet. Techniques that can be used to minimize waste volume are:

  1. Separate "exempt" (liquid scintillation media containing less than 0.05m Ci/g H-3 and C-14) waste from other wastes generated.
  2. Be certain that just radioactive waste is placed in RPS containers. If in doubt, a wipe survey or instrument survey of the item can determine if the material is radioactive. Also, if only a small area of an item (lab bench soaker, for example) is radioactive, dispose of only the contaminated portion to radioactive waste.
  3. Waste containing short-lived radioisotopes such as P-32 or I-125 can be stored until decayed. Several "Decay in Storage Areas" have been designated on campus for this purpose if storage in the laboratory poses a problem.
