radon exhalation rate in surface soil of graduate's villages in west nile delta, egypt, using can technique

Radionuclides distribution and radiation levels are important to assess the potential hazard of radiation exposure. Radon concentration and exhalation rate from surface soil were carried out in totally thirty points with different locations of Graduate’s Villages West Nile Delta, Egypt. Radon concentration and radon exhalation rate were measured using Can technique with CR-39 detector. The average values of radon concentrations ranged from 236.34 to 717.78 Bqm-3 and area exhalation rate from 0.28 to0.86 Bqm- 2h-1. The obtained results can be used as reference information to assess any changes in the radioactive background level due to geological processes in the investigated area.
