Dosimeter badges are an essential tool for radiation safety and detection. They measure the amount of radiation exposure a person has received and are commonly used in medical, industrial, and research settings. This article will discuss dosimeter badges, how they work, and why they are essential for radiation safety. A dosimeter badge is a small device worn by a person to measure their radiation exposure. It is typically worn on the chest or arm. It contains a radiation plate sensitive to different types of radiation, such as X-rays, gamma rays, alpha particles, and beta particles.
The badge measures the amount of radiation that passes through it and records the data on a digital display. The data can then be used to determine the amount of radiation exposure a person has received. Dosimeter badges are typically used in medical settings to monitor a patient's radiation exposure during a procedure. They are also used in industrial environments to monitor workers' exposure to radiation from sources such as X-ray machines or nuclear reactors. In research settings, dosimeter badges can measure the radiation emitted from experiments or other activities. The most common type of dosimeter badge is the OSL XBG.
This type of badge uses a TLD (Thermoluminescent Dosimetry) ring to measure the amount of radiation passing through it. The TLD ring absorbs the energy from the radiation and stores it in its crystal structure. When the badge is read, the stored energy is released as light and measured by a photodetector. This data is then used to calculate the amount of radiation exposure. Whole-body dosimeters are also available for measuring total body exposure to radiation.
These devices measure the total amount of radiation that passes through a person's body over some time. They are typically used to monitor patients exposed to high radiation levels in medical settings. UTHealth uses dosimeter badges to ensure staff and patients are not exposed to dangerous radiation. They also use them to monitor research activities and ensure experiments are conducted safely. Using dosimeter badges ensures that staff and patients remain safe while conducting research or receiving medical treatments. Dosimeter badges are an essential tool for radiation safety and detection.
