SURVEY OF TERRESTRIAL RADIATION LEVELS OF ONNE SEAPORT, RIVERS STATE, NIGERIA
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2012, Vol 1, Issue 3
Abstract
A terrestrial radiation survey of the Onne seaport in Rivers State of Nigeria has been carried out. The area under study was divided into two locations, and investigated. An insitu measurement approach was adopted using Nuclear Radiation Meter (Radarlerst – 100) and a handheld Global Positioning System (GPS 76 CSX) equipment. Ten (10) readings were taken in each of the two locations making a total of twenty (20) readings in all.The measured average background radiation levels ranges between 0.010mR/hr (0.0045mSv/week) to 0.021 mR/hr (0.00g3mSv/week) in the area. The average dose equivalents obtained for most locations within the study area is above the standard background radiation of 0.013mR/hr (ICRP, 1994) but is within the safe radiation limit of 0.02mSv/week recommended by UNSCEAR, (1998). However, results obtained do not indicate any immediate health side effects on the staff and the host communities (Avwiri et al, 2007) as the highest radiation exposure level of 0.0093m/wk recorded is below the recommended value of 0.2mSv/wk by the Texas Regulation for Control of Radiation and Protection of Public Health. (UNSCEAR, 1998).
