Noneho ko ushobora kubara igipimo uhabwa, ugomba kumenya igipimo gifite akamaro. Ingingo nyinshi zisubiramo n'ibitabo by'inyigisho bikunze kuvuga ko igipimo kiri hagati ya 0.1J/cm² na 6J/cm² ari cyo cyiza ku turemangingo, aho kutagira icyo ukora byinshi bikuraho inyungu.
Ariko, hari ubushakashatsi bwagaragaje ibisubizo byiza mu ntera iri hejuru cyane, nka 20J/cm², 70J/cm², ndetse no hejuru nka 700J/cm². Birashoboka ko ingaruka zikomeye ku mubiri zigaragara ku ntera iri hejuru, bitewe n'ingufu zikoreshwa ku mubiri wose. Birashoboka kandi ko n'intambwe iri hejuru igira akamaro kuko urumuri rwinjira cyane. Kubona dose ya 1J/cm² mu ruhu bizatwara amasegonda gusa. Kubona dose ya 1J/cm² mu mitsi miremire bishobora gufata igihe kirekire inshuro 1000, bigasaba 1000J/cm²+ ku ruhu ruri hejuru.
Intera y'urumuri ni ingenzi cyane hano, kuko igena ubucucike bw'urumuri rugera ku ruhu. Urugero, gukoresha igikoresho cy'urumuri rutukura kuri cm 25 aho gukoresha cm 10 byakongera igihe gisabwa cyo gukoresha ariko bigatwikira agace kanini k'uruhu. Nta kibazo kirimo kugikoresha uri kure, gusa menya neza ko wacyishyura wongeyeho igihe cyo gukoresha.
Kubara igihe cyo gukora imyitozo
Noneho ugomba kumenya ubucucike bw'ingufu z'urumuri rwawe (zitandukanye bitewe n'intera) n'ingano wifuza. Koresha formula iri hepfo kugira ngo ubare amasegonda mangahe ugomba gukoresha urumuri rwawe:
Igihe = Ingano ÷ (Ubucucike bw'ingufu x 0.001)
Igihe mu masegonda, urugero muri J/cm² n'ubucucike bw'ingufu muri mW/cm²
