New Trend in Radiation Dosimeters

Abstract

A radiation dosimeter is a device that measures exposure to ionizing radiation. It is used for human radiation protection as a measurement of dose in both medical and industrial processes. This study aimed to identify and highlight the new technology in the types of radiation dosimeters. The study comprises a personal selection of recent reports from radiology journals and Medline searches which highlighted the new trend in radiation dosimeters. Radiation dosimeters and dosimetry systems come in many shapes and forms. They rely on numerous physical effects for storage and readout of the dosimetric signal. The four most commonly used radiation dosimeters are: Ionization chambers; Radiographic films; Thermoluminescent dosimeter systems (TLDs); Silicon diode dosimetry systems (Diodes). There are a variety of electronic dosimetry systems that can monitor any work environment. Electronic dosimeters protect the wearer from the harmful effects of radiation by tracking changes in exposure and keeping an ongoing record of the user’s dose over time. Combined with access control systems, it is possible to limit total exposure to radiation and control access to radiological areas. Dosimetry readers, ensure accurate radiation exposure monitoring. Manual and automated systems for whole body, extremity, neutron, and environmental monitoring are easy to operate, service, and maintain. Extremity dosimeter is a disk dosimeter designed for nuclear power or nuclear medicine personnel that have a high risk of exposure to ionizing radiation, particularly on their hands, due to their work in close proximity to radiation materials and radiation producing equipment.
