All unescorted irradiator users will follow the U.S Nuclear Regulatory Commission and Maryland Department of the Environment regulations for use of the experimental irradiators in the Kimmel Cancer Center.
Those individuals requiring immediate use of the irradiators will need to work with someone that already has approved access (escort). It is mandatory that this approved person accompany you during your use of the irradiator. You may work with an approved person while you are applying for your own access.
If your use of the irradiator will be limited (3-4 times), you do not have to go through the approval process, but you will use the irradiator with someone already approved.
If you have been in the US for less than one year, you cannot apply for unescorted access.
Everyone requesting unescorted irradiator access requires a background check and fingerprinting. This process can take up to 60 days.
To begin the approval process:
1. Email Carl Granlund at firstname.lastname@example.org with the following information:
Name, email, lab, principal investigator, and start date of employment with Johns Hopkins.
2. You will be emailed directions for completing an online security check.
3. You will be notified by email when the next fingerprint session is scheduled (one session per month).
When your background check and your FBI fingerprints/history are completed, you will be notified by email regarding your approval. If you have questions on the approval process please contact Carl Granlund, Radiation Control Unit at (443 28)7-7303.
A dosimeter (radiation monitoring badge) is not needed to enter irradiator rooms or to use irradiators. There is a permanently assigned dosimeter inside each irradiator room
