Measurement of Gross Alpha Contamination in Soil Sample by Using Solid State Nuclear Track Detector (SSNTD) Technique

The measurements of gross alpha contamination (or radiation) in soil samples collected from various locations in the environment of shahjahanpur District was carried out by using LR-115 type II solid state nuclear track plastic detector. Observed result shows that the overall average value of gross alpha contamination was found varies from 20.10Bq/m3 to 36.90Bq/m3 with an average value of 29.06Bq/m3and standard deviation is 8.53 Bq/m3. The value of gross alpha contamination was found maximum (34.32Bq/cm3) at location P and minimum (21Bq/m3) at location R. The present study indicates that the nature of soil in the study area has a very low level radiation. Measured values of gross alpha contamination in soil samples collected from different locations in the study area were found below the world action level (137Bq/m3). Thus the study area is safe from radiation protection and as far as the health hazard effect point of view.
