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.
