MEASUREMENT OF BACKGROUND RADIATION IN IPERINDO TOWN, OSUN STATE

MEASUREMENT OF BACKGROUND RADIATION IN IPERINDO TOWN, OSUN STATE
 
ABSTRACT
Humans are exposed to radiation in their environment with or without their consent; and the exposure to natural background radiation is an unpreventable event on earth. This present study has measured the background radiation in Iperindo town as a result of mining activities from the surrounding goldmine using the Radiation scanner 500VBR. In each location, at least 5 readings were taken in order to ensure reliability of data. The mean absorbed dose rate in air was estimated to be 165.30±22.02 nGy/hr. The Annual Effective Dose rate was found to be 0.301±0.040 mSv/yr while the Excess Lifetime Cancer Risk was gotten as (1.201±0.160) x10-3. The details of the Research procedure and estimation of values are presented and analysed in this work. This work can be used as a baseline research data for further research work, serving as reference for dosimetry in the event of futuristic action against the menace of harmful radiation.
