A Comparative Study Of Gamma Radiation Level Selected In Industries In Jos Plateau State, Nigeria

Mangset E.W, Christopher L.D, Olawusi S


In this research work, a comparative study of the gamma radiation dose level in different industries in Jos and environs was carried out. A Digital radiation detector (gamma Scout of a standard version GS2 –model with a serial number A20) was used to carry out the measurement in the industries. The industries were categorized as communication, mining, Timber milling shades, Food processing, printing press and other industries. The gamma radiation dose levels in communication industries ranged from 0.561 – 2.435 mSv/yr, mining industries from 35.522 – 40.813 mSv/yr, Timber milling shade from 0.613 – 2.961 mSv/yr, Food processing industries from 0.823 – 1.901 mSv/yr, Printing industries from 0.821 – 1.524 mSv/yr and other industries ranged from 1.034 – 3.600 mSv/yr. The highest dose level of 40.813 mSv/yr was measured at Tin processing shade in Utan, Rock Haven and lowest dose of 0.613 mSv/hr at one of the communication masts.

Key words: Gamma radiation, industries, ionizing radiations, Background radiation.
