Radiation monitoring involves the measurement of radiation dose or radionuclide contamination for reasons related to the assessment or control of exposure to radiation or radioactive substances, and the interpretation of the results. [1] The U.S. Navy monitored radiation from the Fukushima I nuclear accidents
Radiation monitors in general have a number of process-control applications in nuclear power plants; [9] a major CPAM application in this area is the monitoring of the air intake for the plant control room. In the event of an accident, high levels of airborne radioactivity could be brought into the control room by its HVAC system; the CPAM ...
Radiation Portal Monitor (RPM) was designed to detect traces of radiation emitted from an object passing through a RPM. Gamma radiation is detected, and in some cases complemented by neutron detection when sensitivity for nuclear material is desired.
Examples are installed "area" radiation monitors, Gamma interlock monitors, personnel exit monitors, and airborne particulate monitors. The area radiation monitor will measure the ambient radiation, usually X-Ray, Gamma or neutrons; these are radiations that can have significant radiation levels over a range in excess of tens of metres from ...
Nuclear MASINT is one of the six major subdisciplines generally accepted to make up Measurement and Signature Intelligence (MASINT), which covers measurement and characterization of information derived from nuclear radiation and other physical phenomena associated with nuclear weapons, reactors, processes, materials, devices, and facilities.
Satellites rely on sensors to monitor radiation from nuclear explosions that always produce gamma rays, x-rays, and neutrons. [3] Nuclear explosions release a massive burst of x-rays that occur repeatedly with an interval of less than 1 microsecond that could be detected by the satellite. [19]
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
A neutron monitor is a ground-based detector designed to measure the number of high-energy charged particles striking the Earth's atmosphere from outer space.For historical reasons the incoming particles are called "cosmic rays", but in fact they are particles, predominantly protons and Helium nuclei.
