أستخدام كواشف االثر النووي لمحالة الصمبة في قياس تراكيز غاز الرادون في التربة في منطقة التويثة

Abstract

Solid state nuclear track detectors was used in measurement of different environmental applications and measuring radioactivity of environmental models such as soil and because of the high sensitivity and efficiency of this technique for recording the tracks of charged particles such as (Protons, alpha particles and fission fragments).Radon gas from environmental pollutants that cause serious health problems that began attention to the problem of pollution radon gas (222Rn ) and thoron gas(220Rn) and the great danger resulting from the exposure of these isotopes through alpha particles emitted , which has demonstrated the relationship between exposures to the divorced alpha particles with the occurrence of lung cancer. In this study measurement of radon Concentration (222Rn) in soil models within the depths (0-5cm) of the soil Surface in the city of Baghdad (the Tuwaitha) and some surrounding units for year (2003). Measuring radon concentration (222Rn) in all regions studied, had reached its highest value in the depth (0-5cm) in the Al-Wardya (268.7799 Bq/m3) (1) and the least value were Siada village (33.2779 Bq/m3) (6) regions of the study showing.
