Abstract |
|
|
| Almost food of all kinds contains radionuclides in varying amount depending largely upon local geology, agricultural practices and climate of the area. Usually these radionuclides are transferred from soils to the crops and water to fish. Plants take up radioactive material contents with the nutrients needed for their growth. On consumption, these products may expose peoples to unwanted radiation. For this purpose, it is appropriate to know the Radionuclides concentrations in food and drinking water and to take necessary actions in controlling their distributions. This review article presents overview of the medicinal plants Radionuclides concentration data obtained across the globe in different studies. Data of different Radionuclides viz.210Po, 210Pb, 226Ra, 232Th, 238U, 222Rn, 220Rn, 40K, 90Sr and 137Cs, have been summarized for the sake of readers ease and interest. In literature, many studies have also reported transfer factor (TF) of radionuclides from soil to plant and estimated the values of average annual committed effective dose (AACED) due to the ingestion of Radionuclides present in medicinal plants. Knowledge of TF is very important in order to get reasonable predictive estimates for Radionuclides concentrations and resulting radiation doses received by public from agricultural crops. These studies are source of baseline data that might be used in any radiological emergency or to formulate regulations related to radiological healthcare for medicinal plants of local origin. |
