Dosimeters are essential tools designed to measure and record an individual's exposure to ionizing radiation. Ionizing radiation includes forms of radiation that have enough energy to remove tightly bound electrons from atoms, potentially causing cellular damage and health risks when exposure levels exceed safety limits. These are crucial in industries such as nuclear power plants, medical radiology, and nuclear medicine to ensure that workers are not exposed to harmful levels of radiation. Regular monitoring helps prevent long-term health risks. In medical settings, dosimeters help ensure that patients receive the appropriate dose of radiation during diagnostic imaging and radiation therapy. Precise dosing is vital to both effective treatment and minimizing radiation side effects.
