This paper describes a new version of the measurement of the calibrati
on factor, K, between radon activity concentration and track density.
The use of Solid State Nuclear Track Detectors (SSNTDs) is out of the
most convenient techniques to assess the radiation level of alpha-acti
vities in the environment. Exposed plastic films are chemically and el
ectrochemically etched in an alkali solution and the alpha-tracks are
evaluated under an optical microscope. The detailed procedure for this
study and the caliabration of the etched films for conversion of trac
k density to radon exposure in (Bq . m-3) are given in this paper. It
was found the experimental and theoretical values of K were 1.37 and 1
.27 (track . cm-2 . kBq-1 . h-1 . m3), respectively, for plastic detec
tors CR-39.
