Assessment of Gamma Radiation Level in Science Blocks in University of Uyo, Nigeria %K Gamma Radiation %K exposure %K Annual dosage %R 10.5829/idosi.ijee.2017.08.01.12 %X The exposure level of gamma radiation and its consequent annual dose rate from the blocks faculty of sciences University of Uyo, Nigeria were investigated.  An in -situ measurements of the exposure level were conducted using Radex radiation meter model RD 1212. The mean exposure measured for the different locations within the departments  ranged between 0.096 ± 0.003 µSv/h µSv/h  to  0.140± 0.007 µSv/h  and the corresponding calculated annual dose rate (ADR ) ranged between   0.742 ± 0.021 mSv/y to  0.981± 0.049 mSv/y with department of chemistry contributing the highest value. Taking the football field as the reference site, the results show that the presence of  chemicals have  slightly increased the radiation level in the studied area; but not large enough for being concern as the annual dose rate is below the acceptable dose limit of 1mSv/y for the public and 20mSv/y occupational limit for personnel in the department. The area of study is new hence it is recommended that routine radiation level monitoring should be carried out for possible rise in the radiation level to be observed. For the safety, it is recommended for staff and students should spend less time indoors. The proper application of gamma rays are used for sterilization and cancer therapy. %U https://www.ijee.net/article_64666_0fc3acf2005e67732858956777601ea8.pdf
