Radiation Detection and Measurement Principles

Ionizing radiation cannot be seen or sensed by the body in any other way. Therefore, nuclear instruments have been used to detect and measure various types of radiation.

Dosimeter

A personal dosimeter, for example the TLD (thermoluminescent dosimeter) badge, measures beta, gamma/x-ray and/or neutron radiation with the highest efficiency (100% grade lithium fluoride). After use, the lithium fluoride elements are heated causing them to luminesce in proportion to the amount radiation exposure.
