What is the purpose of a radiation dosimeter badge?

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.

Why does the x-ray department wear radiation badges?

A radiation badge ensures that professionals who work near any radioactive material can monitor their individual exposure levels throughout their shifts. Being able to measure radiation levels helps to protect them from absorbing an excessive amount of radiation, despite being exposed.

Are x-ray 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 effect does x-ray radiation have on the film badge?

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.

Where do you wear an xray 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.

What is dosimeter radiology?

Dosimeters are a form of devices to monitor ionizing radiation. They are used regularly for a number of key roles including both patient and personal dosimetry, environmental monitoring, spectroscopy, radiopharmaceutical and equipment checking.

What is in a radiation badge?

Radiation monitoring devices are provided by the Radiation Safety Office to measure an individual’s radiation exposure from X-ray or radioactive sources. The standard monitoring device is a clip-on dosimeter badge or ring badge bearing the individuals name & date of the monitoring period.

What is the purpose of personal dosimeter?

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.

How does a dosimeter work?

A thermoluminescent dosimeter measures ionizing radiation exposure by measuring the intensity of light emitted from a Dy or B doped crystal in the detector when heated. The intensity of light emitted is dependent upon the radiation exposure.
