The Nuclear Regulatory Commission has issued an order which mandates that all persons with unaccompanied access to irradiators must now be fingerprinted and undergo an FBI criminal background check. This is in addition to the checks which are already carried out. The order can be found by following this link:

Due to homeland security concerns, the Nuclear Regulatory Commission has issued new regulations that require additional access restrictions for irradiators. 

Due to these new regulations, each employee or student needing to use an irradiator must complete an application and receive approval from Environmental Health and Radiation Safety, even if they currently are approved to use the irradiator.

There are different requirements for employees depending on how long you have been employed at your current institution.

Please select your institution/employer for an application form (pdf):
(Example: A Penn employee working at CHOP should complete the UPenn form)
