Dosimeters
Updates to Article Attributes
Dosimeters are a form of devices to monitor ionising radiation. They are used regularly for a number of key roles including both patient and personal dosimetry, environmental monitoring, spectroscopy, radiopharmaceutical and equipment checking.
Function
Energy enters the dosimeter which converts this energy into a signal strength and an output. The conversion process and the output are unique to each different type of dosimeter.
Common output modalities are:
-
dose rate: gives an instantaneous value over time
often used in environmental, radiopharmaceutical and equipment checks
-
total dose: the amount of activity over a given time frame
patient or personal dosimetry
Types of dosimeters
-
charge collection devices: radiation energy is converted to electric charge (either directly or indirectly) and the dosimeter converts this charge into a signal output
solid-state detectors
-
other type: devices made of material that changes on exposure to radiation energy
