Determination the concentration of radon in human urine using LR-115 detector

In the present study twenty samples of human urine were takenfrom healthy male and female with different of: ages, occupation andplace of residence. These samples were collected from the hospital tomeasure the concentration of radon gas in human urine by using oneof solid state nuclear track detectors LR-115.The results obtained of the concentrations of radon in healthy humanurine are varying from 2.12×10-3 Bq.l-1 to 4.42×10-3 Bq.l-1 andthese values are less than the allowed limits 12.3×10-3 Bq.l-1.
