Abstract |
|
|
| Thirty three samples were collected from four different areas at the Southeastern Desert of Egypt to estimate the values of the radon emanation coefficient of the rocks at these areas. The chosen areas are; Abu Dabbab, Abu Rusheid, Nuweibi and Um Naggat. CR-39 SSNTD fixed at the top of a radon chamber with the crushed sample at the bottom was employed to achieve this work. The results averaged the values of the emanation coefficient into two categories; one includes the rocks from Abu Dabbab and Nuweibi with a value of 0.027 and the other with a value of 0.008. The difference in the values of the emanation coefficient may be ascribed to the difference in the other properties of the rock grains. However, the isolation of these parameters may reveal experimentally a reciprocal relationship between the emanation coefficient and the radium activity in the rocks. |
