Add environmental radiation contact scar and Radial-stricken Workers in Nuclear Industry and public's contact radioactive pollution and the possibility shone.To comment
Harm caused by valency radioactive pollution, it is the most frequently used to carry out radioactivity monitoring to empty gas and water and biology in environment etc.
Means.Problems faced in the measuring method of gross activity and its measurement will be briefly introduced in water herein.
Water Radionuclide is generally divided into stable nuclide and the major class of unstable nucleic two.Unstable nucleic by radioactive decay from
Hair ground discharges α particles, β particles, γ photons and other rays out of core, so as to decay as another element.α, β are penetrated
Line by direct or indirect ionization, can make the molecule of human body occur ionization or excite, and produce a variety of free radicals and work
Chemoattractant molecule, the serious damage and death that also result in human body cell or body.Because the range of α, β particle is short, it is to human body
Interior irradiation of the injury mainly by the generation such as sucking, eating.In people's internal deposition, interior shine easily is produced to human body for part nucleic
Penetrate, and interior irradiation is mainly what is caused by α, β particle, therefore, the measurement to α, β corpuscular radiation is significant.α, β low emission
Property measuring appliance be device conventional at present, but present detector exists complicated, and wiring is difficult, puts inconvenient asks
Topic.This problem can be solved there is presently no a kind of device.
