Abstract
In the present work, effective radium activity, radon exhalation rates and uranium in
medicinal plants have been measured,samples collected from Iraqi markets. Sealed cup
technique containing CR-39 solid state nuclear detector was used. Radium concentration varies
from (0.0297±0.004) Bq/kg to (0.327±0.126) Bq/kg with an average of (0.142±0.025) Bq/kg.
The radon exhalation rate in terms of area varies from (2.287±0.384) μBq/m2.d to
(25.193±9.729) μBq/m2.d with an average of (10.986±1.989) μBq/m2.d, while uranium
concentrations were ranged from (0.018±0.002) ppm to (0.202±0.057) ppm with an average
(0.087±0.002) ppm. The values of radium concentration ,exhalation rates and uranium in all the
medicinal plants samples were less than the recommended by the Organization of Economic
Cooperation and Development (OECD) , United Nations and Scientific Committee On The
Effects Of Atomic Radiation (UNSCEAR) respectively. The results have revealed that the
radium and uranium concentration as well as exhalation rates in studied medicinal plants and
the associated exhalation radon does not pose risk to human health.
