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 Irving Medical Center Campus, New York 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.
Dosimeter Application Form Link
In order to maintain our goal, we request that all dosimetry program participants wear their badges as instructed and return their dosimeters within 14 business days of the end of each wear period (this date is printed on the face of all dosimeters).
Effective April 2018, Landauer, the company that provides Columbia University’s dosimeter badges and reports, has transitioned to a paperless reporting system. All dosimetry reports are available online at www.myLDR.com. These reports will continue to be reviewed by Radiation Safety. Each Principal Investigator, laboratory manager, dosimetry coordinator, and/or designated individuals will receive login information for the Landauer website to access their group’s dosimetry records. Any individual issued a dosimeter badge can login to the Landauer website and view their own radiation dose history following the directional guide: Individual Dose Instructions
Return all dosimetry badges to:
Radiation Safety – CUIMC 630 West 168 Street, EH&S, Mail Code: 70, New York, NY 10032
