Personal dosimeters (radiation monitoring badges) are used by employees and students to gauge the levels of radiation, if any, to which they are exposed. The badges are sent to a contracted company to be read; then, the Radiation Safety Office (RSO) evaluates the readings to verify that exposures are safely below regulatory limits. This is the most important reason for returning all badges to the RSO at the designated end of the wear period: the longer a radiation dosimeter remains unread, the less useful it becomes as a tool for evaluating an individual’s radiation exposure level. Another reason is that the RSO is billed when badges are not returned in a timely manner- within 30 days - resulting in increased program cost.
The RSO must be notified in writing if your badge is lost, stolen, if you move into another department or if you are planning to leave your job. The “Employee Changes/Cancellations Form” is located on our website at http://ehs.columbia.edu/RadiationFormsMC.html, and must be submitted to the RSO in person or by email to email@example.com. Your badge will be deactivated, and an accurate, updated list of current badge users can be maintained. You should also return dosimeters that are old or outdated, even if they are for someone who is no longer with the institution.
The most recent dosimetry reports are to be posted in every department by the supervisor or badge coordinator in an area where employees can view their exposure levels. For further questions about your badges or personal dosimetry in general please email firstname.lastname@example.org or call the RSO at 212-305-0303.
