| Abstract | ||
| The Nuclear Materials Authority (NMA) is carrying out a spectral aerial radiation survey of some areas in the Arab Republic of Egypt in order to achieve two objectives: the detection of new areas for the existence of radioactive elements and environmental impact survey of these elements on the inhabitants of these areas, which is what happened in this area. After the aerial survey of these areas, the locations with high anomalies are tracked on land until they are verified and assessed. One of these areas studied is Ramlet Homayyer, which is located between longitudes 33o 30/ 30// E and 33o 32/ 30// E and latitudes 29o 0/ 30// N and 29o 1/ 30// N. In the current study, ground survey was performed using GS-512 gamma rays spectrometer along N-S profiles, with average length of about 2.5 km. The maximum values of equivalent uranium (eU), equivalent thorium, potassium (K) and Total-Count are approximately 84.0 ppm, 68.9 ppm, 16.0% and 101.3 Ur, respectively. The exposure rate varies in values from 6.6 mR/ h to 131.8 mR/ h, with an arithmetic mean 10.4 mR/h. The dose rate varies in strength from 0.5 mSv/y to 10.9 mSv/ y, with a computed arithmetic mean reaching 0.8 mSv/ y. | ||
