IEC 62327:2006 – Radiation protection instrumentation – Hand-held instruments for the detection and identification of radionuclides and for the indication of ambient dose equivalent rate from photon radiation.
Civil defense Geiger counters, handheld radiation monitors, both G-M and ion chambers; Counting efficiency the ratio of radiation events reaching a detector and the number it counts; Data sonification, the interpretation or processing of data by sound; Dosimeter, a device used by personnel to measure what radiation dose they have received
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.
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.
Hand-held ion chamber survey meter in use. Portable instruments are hand-held or transportable. The hand-held instrument is generally used as a survey meter to check an object or person in detail, or assess an area where no installed instrumentation exists. They can also be used for personnel exit monitoring or personnel contamination checks in ...
Ion chambers are widely used as hand held radiation survey meters to check radiation dose levels. Proportional counters use a geometry with a thin positively charged anode wire in the center of a cylindrical chamber. Most of the gas volume will act as an ionization chamber, but in the region closest to the wire the electric field is high enough ...
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 ...
Hand-held integral ion chamber survey meter in use View of sliding beta shield on integral hand held instrument. Ion chambers are widely used in hand held radiation survey meters to measure beta and gamma radiation. They are particularly preferred for high dose rate measurements and for gamma radiation they give good accuracy for energies above ...
