Na oké osimiri nke ọmụmụ na n'akụkụ abụọ nke ekwentị radiation nsu na-ahapụ ndị na-azụ ahịa mgbagwoju anya, e nwere otu ọkọlọtọ na-enyere gị aka ikpebi na gọọmenti na-edebere radiation level nke ekwentị gị. A na-akpọ SAR.
SAR bụ "ụzọ iji tụọ ọtụtụ redfrequency (RF) ike nke anụ ahụ na-etinye na ya," dị ka Ụlọ Ọrụ Ndị Ọrụ Na-ahụ Maka Ịntanetị na Cellular (CTIA) dị.
SAR na-anọchi anya ọnụego absorption . Nbelata SAR ekwentị gị, belata ntanetị ikuku redroma gị na ya nwere ike inwe ahụike dị na ya na iji ekwentị gị.
Na North America, a na-atụle sar SAR ekwentị n'etiti 0.0 na 1.60 na 1.60 nke Federal Communications Commission (FCC) setịpụrụ dịka ọkwa kachasị nke radieshon kwere.
CTIA chọrọ igwe ekwentị niile na United States iji rube isi SAR a site n'aka FCC.
Na Europe, ọkwa SAR si na 0.0 ruo 2.0 dị ka European Union Council kwadoro ya, nke International Commission on Non-Ionizing Radiation Protection (ICNIRP) kwadoro.
Na North America, a na-atụ SAR na watts kwa kilogram (ma ọ bụ W / kg) dị elu karịa otu mkpụrụ nke anụ ahụ dị ndụ ma na SAR dị na SAR dịka 10 grams.
Njedebe FCC, nke na-agbapụta ihe karịrị otu gram nke anụ ahụ, dị nnọọ njọ karịa ndị ọzọ nke ụwa.
Dị ka ihe atụ, iPhone 3G , nwere ọkwa SAR dị elu nke 1.388. Motorola owuwe VU30 na- akọ ọkwa SAR dị ala nke 0,8 n'isi na 0.78 na ahụ mgbe LG enV 2 na- akọ ọkwa SAR dị elu nke 1.34 na isi na 1.27 na ahụ.
Na mgbakwunye na iji aka na-ahọrọ ekwentị nwere ọkwa SAR dị ala, ị nwekwara ike belata mgbasa ozi radiation site na iji ekwe ntị wireless Bluetooth ( dị ka nke a ) iji gbochie ekwentị gị n'isi ma ọ bụ jiri olu ekwenti ekwentị gị .
