It detects ionizing radiation such as alpha particles, beta particles, and gamma rays using the ionization effect produced in a Geiger–Müller tube, which gives its name to the instrument. [2] In wide and prominent use as a hand-held radiation survey instrument, it is perhaps one of the world's best-known radiation detection instruments.
The relative efficiency of germanium detectors (including other types of detectors) are frequently compared to a standard 3 × 3 sodium iodide detector, representing 100% relative efficiency. Various measurements have shown that cerium bromide (CeBr 3 ) has improved efficiency and resolution compared to sodium iodide, with comparably low ...
Victoreen Civil Defense V-777-1 shelter radiation detection kit overview. CD Counters came in a variety of different models, each with specific capabilities. Each of these models has an analog meter from 1 to 5, with 1/10 tick marks. Thus, at X10, the meter reads from 1 to 50. CD meters were produced by a number of different firms under contract.
The CD V-700M is a Model 6/6A/6B modified with an OCD-P-108 probe fitted with an OCD-D-109 GM tube that enables the detection of alpha radiation, in order to aid in decontamination. ENI 6B's were most commonly used, though some Victoreens were converted as well.
Survey meters in radiation protection are hand-held ionising radiation measurement instruments used to check such as personnel, equipment and the environment for radioactive contamination and ambient radiation. The hand-held survey meter is probably the most familiar radiation measuring device owing to its wide and visible use.
Photographic plate (Nuclear emulsion) Detectors for radiation protection. The following types of particle detector are widely used for radiation protection, and are commercially produced in large quantities for general use within the nuclear, medical, and environmental fields. Dosimeter; Electroscope (when used as a portable dosimeter)

Hand-held scintillation counter reading ambient gamma dose. The position of the internal detector is shown by the cross. Radioactive contamination monitors, for area or personal surveys require a large detection area to ensure efficient and rapid coverage of monitored surfaces. For this a thin scintillator with a large area window and an ...
