In present study, natural levels of radon-222 in forty selected herbs with medicinal
properties present in many stores throughout Iraq were measured to establish any
potential radiation hazards. The Solid State Nuclear Track Detectors SSNTDs (CR-39)
technique was used to determine these natural levels of radiation. The findings indicate
that the radon concentrations ranged from 10.6602.07 Bq/m3 to 53.3034.64 Bq/m3 with
an average 26.5373.21Bq/m3. These radon concentration values were lower than those
reported in literature. These results show that consumption of the studied plants would
impose no health threat to the consumers.
