Ig. Abdullaev et al., INDOOR AND OUTDOOR RADON MEASUREMENTS IN SOME REGIONS OF TAJIKISTAN AND EUROPEAN RUSSIA, Radiation measurements, 28(1-6), 1997, pp. 739-740
The measurements of Rn concentrations in some seismically active regio
ns of Tadjikistan and more quiet central parts of European Russia were
performed during September and October 1995. Alpha sensitive CR-39 pl
astics were exposed during 30 days in standard Rn collectors of 100 mm
height and 60 mm diameter. Organic membranes which prevent registrati
on of short lived alpha decaying nuclei of Th chain of radioactive dec
ay were placed at the open sides of Rn collectors. The preliminary dat
a on Rn level measurements are presented.
