Radiation detection monitoring


The threat of radiation from a radioactive material is very real and, thus, the need to detect the risk as soon as possible. This threat is present either on the battlefield, on the land or in the sea. Equipment have been developed and used, especially in the military field; equipment specifically built to fit the aspects of reliability hardened and with regard to the durability of the military standards. Such equipment includes the personnel dosimetry, area and air monitoring equipment, radiation survey meters as well as a range of specialized identification and search equipment.


This is a small radiation monitoring device that is usually worn by persons entering environments that are assumed to have radiations. Nuclear power or nuclear medicine personnel working in near proximity to radiation materials and radiation producing equipment can use this equipment to detect and monitor radiation levels. The Dosimeter can be worn mostly on hands, on adjustable rings and on wristbands to detect and measure skin radiation on the fingers or wrists; indicating places where radiation is high.

Survey meters

They are portable handheld radiation detection and measurement instruments. Survey meters are mostly used in checking of personnel, equipment, and facilities for radiations as well as the determination of external radiation fields in measuring the level of exposure. They are the most widely used, mostly to their visibility and the fact that they give one’s proximity to possible radiation sources.

Geiger counter

Geiger counter is equipment used for measuring ionizing radiation by detecting the radiation (ionizing) that entail beta particles, gamma rays and alpha particles by use of the ionization effect produced in a Geiger–Müller tube of the equipment. The tube gives the instrument its name. It can be used to detect radiation within a relatively wider range. The tube has two major limitations of inability to differentiate between radiation types and the inability to measure high radiation rates.

Ionizing chamber survey meter          

Ion chamber survey meter is a type of survey meter that collects charges in the immediate environment and, thus, able to detect radiation. It can detect and produce a weak output signal to the user that usually corresponds to the number of ionization events in the environment. Stronger energy output is a result of increased levels of radiation, intensifying the level of activity, leading to a stronger signal. It, thus, can show the presence and the strength of radiation in the surrounding.

Radiation portal monitors

These radiation monitors are considered the first measure in the prevention of the illicit trafficking of radioactive and nuclear materials. They are designed for the monitoring of trucks, cars, trains, and other possible radiation sites. Polimaster's automated fixed portal radiation monitors meet the international requirements and specialized standards of nearly all nations they are equipped with video monitoring system, gamma, and neutron detectors; a pager and computer communication system that is responsible for radiation monitoring. The features make it possible to detect even the slightest ionizing radiation sources and keep records of all activities related to the source of the radiation trafficked so long as the place is monitored.
