The following Radiological protection instruments can be used to detect and measure ionizing radiation: Ionization chambers; Gaseous ionization detectors; Geiger counters; Photodetectors; Scintillation counters; Semiconductor detectors
It is widely used in applications such as radiation dosimetry, radiological protection, experimental physics and the nuclear industry. "Geiger counter" is often used generically to refer to any form of dosimeter (or, radiation-measuring device), but scientifically, a Geiger counter is only one specific type of dosimeter.
Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
The instrument used is normally referred to as a whole body counter. This must not be confused with a "whole body monitor" which used for personnel exit monitoring, which is the term used in radiation protection for checking for external contamination of a whole body of a person leaving a radioactive contamination controlled area.

These detectors are rarely used for imaging and are only efficient at low energies. [17] Practical application in medical imaging started in the early 2000s. [18] Amorphous selenium is used in commercial large area flat panel X-ray detectors for mammography and general radiography due to its high spatial resolution and x-ray absorbing ...
In experimental and applied particle physics, nuclear physics, and nuclear engineering, a particle detector, also known as a radiation detector, is a device used to detect, track, and/or identify ionizing particles, such as those produced by nuclear decay, cosmic radiation, or reactions in a particle accelerator. Detectors can measure the ...
