The personal ionizing radiation dosimeter is crucial in the fields of radiation dosimetry and radiation health physics. Primarily used to calculate the radiation dose accumulated in the person wearing the device. A personal Dosimeter is a small device that can use anywhere. The dosimeter does not shield the body from radiation; it is only used for estimation. Radiation is measured by placing a dosímetro personal on a body part.
Personal Dosimeters are classified as follows:
- Modern types
- Legacy types
1. Modern types:
Electric personal dosimeters are more common and extensively used. Electric personal dosimeters have many sophisticated functions, such as continuous monitoring that allows alarm warnings and live readouts of accumulated doses at predetermined levels. These are particularly effective in slightly elevated areas where the wearer’s residence time is limited due to dosage restrictions.
After taking a reading, the electric dosimeter can usually be reset for record purposes. Because of the resetting, this type of personal dosimeter reuses numerous times. Electric dosímetro personal is also known as modern type dosimeters.
2. Legacy types:
Dosimeters are only utilized once per person for film badges. As the film develops, these levels of radiation absorption represent through a visible change in the film emulsion.
They majorly replace electronic personal dosimeters and thermoluminescent dosimeters. It is not extensively useful after use, so it is not suitable for regular reading.
What is the placement of your dosimeter on the body?
The full-body dosimeter can wear in the front of the body, in the core of the torso, or anywhere from the waist to the neck. It can wear on any part of your body that is most comfortable for you. Because it wears on the hand, the ring dosimeter is more convenient for people.
The hand is more likely to be exposed because it is closest to the source of radiation. The vast majority of people would rather wear a ring dosimeter.
Bottom line
Dosimeters are given out to people to measure and record the amount of occupational radiation dose they receive. A dosimeter must be issued if a person is likely to receive more than 10% of the maximum permissible dose.
A person gives a dosimeter. You are not permitted to share your dosimeter with anyone else. You should also avoid wearing the dosimeter of another person. Wear your dosimeter during diagnostic X-rays or any personal medical procedure that involves nuclear medicine isotopes.
