Radiation dosimeters are devices that measure the dose uptake of external ionizing radiation, thereby, enabling the monitoring of radiation exposure to individuals. The NJDEP states that “any individual who is likely to receive a dose in excess of 25 mrem in any period of seven consecutive days” requires the use of individual radiation monitoring devices. Approximately 95% of the individuals who are issued dosimeters at Rutgers University do not receive a measurable dose.

In general, the following uses of radioactive material and/or radiation require the use of radiation dosimeter to measure and monitor exposure to ionizing radiation:

  • Radioiodination protocols using I‑125
  • The use of gamma emitters other than I‑125
  • Cell labeling experiments using greater than 1 mCi P‑32 per experiment
  • The use of X‑ray producing devices (excluding electron microscopes)
  • PET‑CT Use and Particle Accelerator Use
  • Declared pregnant workers (Fetal Dosimetry Program)

The dosimeters that are issued at Rutgers are not capable of monitoring external radiation exposures from the following isotopes: H‑3, C‑14, S‑35
