Dosimetry Badge Use & Misuse

Dosimetry Badge Use & Misuse

Dosimetry Badge Use & Misuse. Many people wear their badges without regard to the guidelines prescribed by their provider. While on a business trip last week, I was eating breakfast when my attention was drawn to a gentleman that had on scrubs and was wearing a film dosimetry badge (one of our competitors). I asked about his badge and he told me that he is a traveling radiation technician and wears the badge all day long.

Three things stood out to me:

1. he was using older film badge technology (technology that is inferior to our TLD badges)
2. he was using a competitor, therefore paying too much
3. he wore his dosimetry badge to breakfast

“Radiation badges” (dosimeters) are designed to be worn on the outside of the clothing, around the chest or extremity during the time the individual is exposed to occupational radiation.

The dose measurement quantity, personal dose equivalent is defined by the International Commission of Radiological Protection (ICRP) as the dose equivalent in soft tissue at an appropriate depth within a specified point on the human body. The specified point is usually given by the position where the individual’s dosimeter is worn and NOT to be worn outside your work or lab related activities. Having your badge while traveling to work, going to lunch, etc. can easily give a false measurement of your radiation exposure.

Whole body and extremity dosimeters are available from Med-Pro, Inc. With a simple phone call, you can register yourself and your employee’s for protection. It can help you the provider stay within state and federal guidelines. Sign up is easy and only takes five minutes.

If you are currently using dosimetry badges, consider the following recommendations:

Wear your personal dosimeter and do not wear another worker’s badge.
Wear your whole body badge between your collar and waist. Wear your ring badge below your gloves with the label on the palm aspect of the hand that handles the radiation supply and so has the best potential for exposure.
Do not store your badge close to radiation sources or heat sources.
If you think your badge has been contaminated, visit your Radiation Safety Officer immediately.
Do not wear your badge once receiving medical radiation exposure (e.g., x-rays, tests, medicine, etc.)
View your dosimetry report often, this should be available online and easy to read. Your personalized report should tell you if you have been exposed to unhealthy doses of radiation. If you need more technical info, go to The RadioChemistry Society.
