Abstract:
Different measurements of equilibrium equivalent concentration of radon progeny (EECRn) were obtained over a period of one year in indoor air of Physics Department at Minia University, located in the Upper Egypt. A method based on an alpha spectroscopy was used. Sartorius membrane filters (1.2 µm pore size, 25 mm diameter and its efficiency about 100%) were used as a collection media. Alpha activities were measured during and after air sampling by using surface barrier detector. EECRn varied between 1.26 and 19 Bq m-3 with an average value of 5.2 ± 0.46 Bq m-3. Unattached fraction was determined using a single stainless steel-wire-mesh screen (50% penetration for 4 nm equivalent diameter). A mean unattached fraction (fb) of 0.08 was obtained. Based on the obtained measured data values (fb and EECRn), dose conversion factors were compared to epidemiology based value of 4 mSv/WLM for indoor air. © (2015) Trans Tech Publications, Switzerland.
