Abstract |
|
|
| In the present work, effective radium content and both area (surface) and mass exhalation rates in beach sand samples collected from eight sea costs locations ( Red Sea and Mediterranean Sea)in Egypt have been measured using the sealed cup technique and LR-115 nuclear track detectors. The values of radium content have been found to vary from 20± to 84±18 Bq kg-1 with an average value of 37±20 Bq kg-1. Area exhalation rate values were found to vary from 4x10-6 to 16.8x10-6 Bq m-2h-1 with an average value of 7.4x10-6 Bq m-2h-1, whereas, mass exhalation rate values were found to vary from 60x10-9 to 252x10-6 Bq kg-1h-1 with an average value of 111x10-9 Bq kg-1h-1. All the results obtained in the present work were found to be less than their corresponding world limits. Thus, the present results have revealed that, radium content and both area and mass exhalation rates in the studied beach sand samples do not pose risk to human health. The results were compared with national and some other countries. |
