  6. Although thoron is one of isotopes of radon, and the characteristics of thoron and thoron progenies are similar to those of radon and radon progenies, because the half life of thoron is shorter ( 55. 6s ), the concentrations of thoron and thoron daughters in environment are lower, people usually think that the effective dose from thoron and its progenies can be eliminated, and the measurements of thoron progenies concentrations are difficulty, a little research work on the dose evaluation of thoron and thoron progenies in environment has been done
