Radiation Safety FAQ's
Who is required to attend Radiation Safety training?
What are the commonly used radioactive materials at Yale?
Can I work with radiation producing equipment or radioactive material if I am pregnant?
How is radioactive material ordered at Yale?
How is radioactive material stored at Yale?
Is there a limit to the amount of radioactive material that can be stored in the laboratory at one time?
Yes. When a Principal Investigator is granted approval to use radioactive material by the Yale University Radiation Safety Committee, certain limits are authorized. The maximum amount to be ordered at one time [in one day] is stated as part of the approval. The maximum amount allowed to be in the possession of one principal investigator at one time is also stated. Note that the total amount of radioactive material in all individual laboratory rooms used by that PI is summed. This total, including waste and experiments in progress in the labs, must not exceed the authorization limits. See your individual PI or the RSS for information about the specific limits in your research group.
