Application

Specification

Portable multifunction scintillation gamma spectrometer AT6101D is designed to measure specific effective activity value of natural radionuclides K-40, Ra-226, Th-232 in construction materials, raw and manufactured products, manufacturing waste and other objects of environment, as well as measurement of Cs-137 surface activity in soils and subsoils, and Cs-137 specific activity in agricultural raw materials, wooden products and construction materials.

In situ measurement are made for 2π and 4π geometries without preliminary sampling.

Operating principle

Detection unit in a shock-resistant, dust-and-moisture-proof container registers gamma radiation of controlled radionuclides. Spectrometric information from the detection unit is transferred into processing unit (PU) and is displayed on LCD screen.
Instrumental spectra processing algorithm allows display data in the form of specific effective activity of natural radionuclides, their concentration and specific activity of Cs-137 (or other optionally).
Ambient gamma radiation dose equivalent rate value in inspection point is determined by instrument spectrum analysis with “spectrum-dose” operational function.

Radioactive anomalies are searched in integral count rate measurement mode.
