ASSESSMENT OF EXCESS LIFETIME CANCER THREAT POSSIBILITY USING THE SURFACE DOSE RADIATION INFORMATION FROM TOWN CAMPUS, UNIVERSITY OF UYO, NIGERIA
Excess lifetime cancer threat possibility is investigated to know more about the health satus of University of Uyo campus. A radiation survey meter (Diligert 200) was the major device used to obtain the primary data. Global positioning system was also used to note the locations and elevations. The locations with the highest Excess Lifetime Cancer Risk (ELCR) are latitudes and longitudes 05002.3141 and 007055.5691, 05002.2981 and 007055.5401, 05002.3161 and 007055.4831
respectively; whose values are above 0.0009 Bqkg-1 but not up to 1.0 x10-3 BqKg-1. The lowest values of 0.000307 Bqkg-1 and 0.000368 Bqkg-1 are noted on latitudes and longitudes 05002.3381 and 007055.5691, 050 02.3001 and 007055.4821 correspondingly. This value is lower than the recommended world average of 1.0×10-3 BqKg-1. Activities encouraging rise in radiological hazard should be discouraged in the University of Uyo Town campus as the highest values obtained, though are not up to maximum standard but really approaching this value.
