ECOTEST MKS-05 TERRA-P+ Operating Manual page 7

Beta radiation is a flow of electrons. Beta radiation obtains higher permeability
and penetrates organism tissues at the depth of 1-2 cm.
Neutron radiation is a flow of neutrons originating from the process of nuclear
fission in the reactors, or as a result of spontaneous division in the nuclear materials.
Since neutrons are electroneutral particles they deeply penetrate any substance,
including living tissues.
However, because people are more often exposed to gamma and beta radiation in
everyday life, the majority of radiation monitoring devices measure exactly these
kinds of radiation. As a matter of fact, the MKS-05 "TERRA-P+" dosimeter-
radiometer, designed on the base of the modern professional dosimeter-radiometer
MKS-05 "TERRA" exported into different countries and remaining an equipment
choice for the Ukrainian force structures, serves to prevent gamma and beta radiation
hazard.
