Dosimetry/Radiation Badges

In general, the following uses of radioactive material and/or radiation require the use of a monitoring badge:

  • 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)
  • Declared pregnant workers (Fetal Dosimetry Program)

The Nuclear Regulatory Commission requires the use of individual monitoring devices by "adults likely to receive, in one year from sources external to body, a dose in excess of 10 percent of the limits in 10CFR20.1201(a)." As the annual whole body limit specified in 10CFR20 is 5000 mrem, the dose at which monitoring is required is 500 mrem. Approximately 94% of the individuals who are issued badges at Rutgers and RWJMS do not receive a measurable dose.

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

If you would like a badge, but do not meet the criteria above, one will be provided to you after REHS receives an internal purchase order from your department for the cost of the badge(s). The cost of a whole body badge is $2.95 per quarter, while a ring badge is $2.65 per quarter.
