Kuongororwa kweSAR (specific absorption rate) kunonyanya kutakurika, senharembozha, mahwendefa, mawachi nemalaptops, nezvimwewo. Kuongororwa kweSAR ndiko kunoreva simba remagetsi rinotorwa kana kudyiwa pachikamu chehuwandu hwemasero evanhu. Yedu BTF bvunzo murabhoritari inoshanda mukuyedzwa kweSAR uye yakashongedzerwa zvakakwana kuti isangane nezvinodiwa zvenzvimbo yebvunzo, pamwe nekuona kuti michina inoenderana nemiganhu yekuchengetedza yakatemwa nevanotonga zviremera. Nekuita SAR kuyedzwa, vagadziri vanogona kuvimbisa kuti zvigadzirwa zvavo hazvikonzere njodzi kune vashandisi.
