Radiation Safety Dosimetry Program



The Columbia University dosimetry program provides radiation monitoring services for various radiation workers and x-ray users within Columbia University Morningside Campus, Columbia University Medical Center Campus, New Y ork State Psychiatric Institute, New York Presbyterian Hospital, College of Dental Medicine and the Lasker Building. Our goal is to maintain all workers’ radiation exposures As Low As Reasonably Achievable (ALARA). Some of the services the dosimetry program provides include: scheduled trainings, in-service refresher trainings, monitoring during pregnancy, and access to exposure histories. Please view our links listed below. 

In order to maintain our goal, we request that all dosimetry program participants wear their badges as instructed and return their dosimeters within 15 business days of the end of each wear period (this date is printed on the face of all dosimeters).

If you are a pregnant radiation or x-ray worker and would like to receive additional radiation monitoring during your pregnancy please complete the Pregnancy Declaration Form  and schedule an interview appointment by calling (212) 305-5359 or emailing
