Why do radiation workers wear a film badge?
A film badge dosimeter monitors your radiation exposure to prevent you from exposure to over 10% of the allowable radiation limit (ALARA). The radiation badge measures the amount of radiation your body is exposed to so that you do not absorb large amounts of ionizing radiation.
Are radiation badges required?
All users of medical x-ray equipment (C-arms, fluoro units, therapy units) must wear badges. Those using larger quantities of radioactive materials will also be provided badges.
What are special detection badges used for?
Badges do not protect you from radiation. The purpose of a dosimetry badge is to document your occupational radiation exposure and demonstrate compliance with annual dose limits and ALARA levels.
Why is it important to wear a dosimeter?
It’s vital to wear a dosimeter or a radiation badge to collect data on the amount of radiation that you are exposed to. It can provide numbers on the accumulated radiation, so you get an idea of the results.
What does a radiation badge do?
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.
How does a radiation badge work?
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.

Are dosimeters mandatory?
Purpose: Dosimeters are issued to measure and record the amount of occupational radiation dose an individual receives as required by state and federal regulations. Dosimeters are required to be issued if an individual is likely to receive greater than 10 percent of maximum permissible dose.
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 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.
What is a dosimeter and why is it used?
dosimeter, instrument that measures exposure to ionizing radiation over a given period. There are three types of dosimeters worn by persons who work with or near sources of radiation. The film badge is the most popular and inexpensive.
How do you use radiation badges?
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. However, if the worker is pregnant, then the badge is worn on the abdominal region and underneath the apron.
When to not wear your radiation monitoring badge?
No matter how curious you are, do not wear your badges when you receive a medical x-ray or other medical radiation treatment. Your badges are intended to document your occupational dose, not your medical dose. If you lose, damage, or contaminate your badge, call EHS immediately for a replacement.
Why do you wear a radiation badge on your head?
It means you are doing the right things in your practice. The reason we wear radiation badges is the same reason we wear a hard hat. Just in case. Not many of us have had something fall on our head at a construction site, but we see the possibility and use a hard hat to protect ourselves.
What’s the minimum radiation dose for a body badge?
This phenomenon is called thermoluminescence and dosimeters that use this principle are often referred to as TLDs (thermoluminescent dosimeters). The minimum reported dose for the body badge is 10 millirems for x-rays and gamma rays. The minimum detectable dose for the ring badge is 20 millirems for x-rays and gamma rays.
What kind of radiation badge do I need at CHP?
The Traditional Radiation Badges we use at CHP The Apex OSL and Genesis Ultra BP TLD we offer measures dose down to 10 mrem, or 1 mrem respectively. A fraction of the natural radiation background (300 mrem/year). If you are getting exposed in the workplace, we will see it.
