A radiation dosimeter or badge does not provide protection but detects and measures radiation that you have been exposed to. The badge will detect high-energy beta, gamma or x-ray radiation. Dosimeters cannot detect low energy beta radiation from some isotopes, including carbon-14, tritium or sulfur-35.A radiation dosimeter or badge does not provide protection but detects and measures radiation that you have been exposed to.

How does a radiation badge detect radiation?

There is a lightproof packet of photographic film inside the badge. The more radiation this absorbs, the darker it becomes when it is developed. To get an accurate measure of the dose received, the badge contains different materials that the radiation must penetrate to reach the film.

How do you read a radiation badge?

If you're wearing a ring dosimeter. The code used is indicated with an S.

Where should you wear your radiation badge?

The Whole Body Radiation Badge is typically worn on the shirt, facing front. It should not be blocked or covered. If you are required to wear a lead apron for any reason, the badge should be worn on the collar outside the lead apron.

How does the control dosimeter badge work?

Control badges provide a background measure of radiation exposure. Control badges should not be worn by a participant and should be stored in the same location as all other issued badges. Control badges should be rotated at the same time as the participant badges.

What are radiation badges called?

A film badge dosimeter or film badge is a personal dosimeter used for monitoring cumulative radiation dose due to ionizing radiation. The badge consists of two parts: photographic film and a holder.

How do you know if the radiation badge exposure is acceptable or unacceptable?

The nametag on the badge is facing away from the body. Wear your ring badge so that the label is facing out from the side of the hand most likely to receive a radiation exposure. If you are wearing gloves, wear the ring inside your glove so the ring does not become contaminated.

How often should radiation badges be changed?

Badges are exchanged quarterly. You should expect to receive your new badges a day or two before the start of each calendar quarter.

How do you wear a radiation ring?

The best place to wear the badge is on the neck or chest facing the radiation source. If the worker has a lead apron, then the badge should be worn over the apron, and not underneath it.

How do you use a radiation dosimeter?

Where to wear your dosimeter: Whole body dosimeters should be worn on the front of the body, in the area of the main torso, anywhere from waist to neck. Individuals who wear lead garments should position the whole body dosimeter at the collar level, outside of any lead protection.
