Module 6: Radiation Monitoring Badge Program
Overview of the Module
This module provides information about the following topics:
At Princeton University, radiation monitor badges are provided to
monitor occupational radiation exposure for those workers who use radiation
under certain conditions. Princeton University monitor badges should not
be used to measure occupational doses received at any other institution or to
doses from non-occupational sources such as medical x-rays.
State regulations require that those persons who are likely to receive 10% or more of the Annual Radiation Dose Limits must be provided with radiation monitoring badges. This means that state regulations require monitoring for any person likely to receive a whole body dose of 500 millrem or more or a skin or hand dose of 5000 millirem or more. Additionally, New Jersey requires monitoring of finger exposures for persons working with analytical x-ray machines.
Under Princeton University requirements, you must wear radiation monitoring badges if:
Examples of how the dosimetry criteria are applied
Temporary badges are available for workers whose high-level radioisotope use is sporadic. EHS maintains a large supply of temporary badges and can supply you with a temporary badge the same day that you request one.
More Information about Monitoring Badges
Monitoring badges are not routinely provided to workers who do not meet the criteria described in the Required Monitoring section. For example, you will not be routinely provided with badges if:
In 2000 Princeton University implemented the radiation monitoring badge criteria
described in the sections above. Prior to the implementation of the current
badging criteria and over the last 30 years, Princeton University provided
radiation monitoring badges to many more workers than we currently do. Prior
to 2000, Princeton University provided monitoring badges to about 600-800
people a year. Typically, 90% of all monitored persons received no measurable
dose. The following table provides information about doses received during
the years 1996-1999:
During this period of time, no one received a dose high enough to require monitoring under federal or state regulations.
More detailed information about internal monitoring procedures is available in Section 6 of the Radiation Safety Manual for Laboratory Workers. If you use radioactive materials under circumstances where there is a reasonable likelihood of taking up radioactive material internally, EHS will contact you to make arrangements to conduct bioassays.
