Study and calculation the concentration of radon gas in Tarmia city, North Baghdad

Abstract

In This work the radon Concentration has been measured in Tarmia city in room of buildings by using The (CN-85) Track detector. The bulk etch. rate (VB), The Track etch. rate (VT), etching efficiency (µ)and Sensitivity were determined at a temperature of (60/oc) using (2,2.5,3) normality of NaOH as a track etching. The Second part of work is the radon and radon daughters' measurements in indoor of buildings Using (CN-85) detector also. The obtained result are illustrate in Table -2- it was Found that radon concentration is (103.99) Bq/m3.
