Search dosimeter-radiometer MKS-RM1401K-3
Description
MKS-RM1401K-3 is a multifunctional device that combines the functions of a search device, radiometer, dosimeter, spectrometer and radioisotope identifier.
Operating principle
One of the smallest and lightest radiometers in the world, which combines the functions of several instruments.
The device provides search, detection and localization of radioactive materials by recording gamma and x-ray (photon), neutron, alpha and beta radiation. Using audio or vibration alarms, the device warns the user when the set thresholds are exceeded.
Using PM1401K-3, the user can measure the DER of gamma and X-ray radiation, as well as the degree of contamination of surfaces with alpha and beta particles. The non-volatile memory of the device stores up to 500 events and up to 1000 accumulated gamma spectra.
The device allows you to identify the radionuclide composition of a substance, as well as measure the specific (SA) and volumetric (VA) activity of radionuclides in samples.
Standard equipment includes
Search dosimeter-radiometer MKS-RM1401K-3, α-radiation filters, USB cable, spacer rings (for measuring α-, β-radiation), clip, 2 AA-LR6 batteries, passport with verification mark and warranty card, packaging, instruction manual (electronic media)
Additional accessories
External vibration alarm (for working in a noisy environment or for covert search), wrist strap for attaching an external vibration alarm, moderator chamber, calibration device, telescopic extension (for examination in hard-to-reach places), Marinelli vessel (for measuring the specific activity of isotopes of cesium-137 radionuclide in liquids and bulk products), tripod (for measuring the specific activity of isotopes radionuclide cesium-137 in liquids and bulk products)
