Effective radium content and Uranium concentrations in some types of dry cleaning
materials samples such as soap and detergent powder from different sources were collected
from the Iraqi markets in this study. A sealed container technique was used depending on
the LR-115 Type II SSNTDs. The results demonstrated that the effective radium content
in the soap ranged from (3.82) Bq/Kg to (39.54) Bq/Kg with an average (13.22 ± 4.70) Bq/
kg, while the effective radium contend in detergent powder and ranged from (6.44) Bq/Kg
to (22.92) Bq/Kg with an average of (15.10 ± 2.92) Bq/kg. The Uranium concentrations of
the soap and powder detergents ranged from (0.21) ppm to (2.52) ppm with a mean (0.79 ±
0.30) ppm and from (0.32) ppm to (1.42) ppm with a mean (0.86 ± 0.19) ppm respectively.
Furthermore, the current results demonstrated that there is a strong correlation (r=0.92)
between effective radium content and uranium concentrations. The effective radium content
and uranium concentrations in the studied samples were lower than the maximum values
recommended by international bodies.
Abstract
Keywords: Effective radium content, Uranium concentrations, cleaning materials and LR-115 detector.
