Assessment of alpha radioactivity and dose estimation in widely used medicinal plants environmental monitoring of afforestation.

This paper reports the presence of alpha radioactivity in a few medicinal plants, which form the main components of some hebal drugs. Assessment of effective dose has also. been done. The total alpha radio activity in medicinal plants has been found within 47 - 245 Bq/Kg and the effective dose found in the range 2.8 - 4.7 µSv. This data is required for environmental monitoring.
