Wax ka sii qor faqradan - Saameynta caafimaad ee shilkii nukliyeerka ee Three Mile Island 1979
aad bay u badan yihiin, laakiin si wada jir ah looma oggola inay aad u hooseeyaan. Ururka Nukliyeerka ee Maraykanka ayaa soo gabagabeeyay in celceliska soo-gaadhista shucaaca ee maxalliga ahi ay u dhiganto shaashadda X-ray ee laabta, iyo soo-gaadhista ugu badan ee maxalliga ah ee u dhiganta wax ka yar hal sano oo shucaaca asalka ah. Warbixinta BEIR ee Mareykanka ee ku saabsan Saameynta Biyoolajiga ah ee shucaaca ionizing waxay sheegeysaa in "dose-ka wadarta ah ee ka dhashay shucaaca sii daayay shilka Three Mile Island uu ahaa mid aad u hooseeya in tirada lagu qiyaasay kiisaska kansarka ee la filayo, haddii ay dhacdo, ay noqon doonto mid la iska indho tiri karo oo aan la ogaan karin". Daraasado kala duwan oo cudurrada faafa ah ayaa lagu soo gabagabeeyay in shilku uusan lahayn saameyn caafimaad oo la arki karo oo muddo dheer ah. Mid ka mid ah daraasadaha ka soo horjeeda waa "dib u qiimeynta dhacdooyinka kansarka ee ku dhow warshadda nukliyeerka ee Three Mile Island" oo uu sameeyay Dr. Steven Wing oo ka tirsan Jaamacadda North Carolina. Daraasaddan, Dr. Wing iyo asxaabtiisu waxay ku doodayaan in natiijooyinkii hore ay lahaayeen "dhibaatooyin macquul ah iyo qaabab" waxayna ku soo gabagabeeyeen in "xanuunka kansarka, gaar ahaan kansarka sanbabada iyo kansarka dhiigga, ay kordheen ka dib shilkii TMI ee meelaha lagu qiyaasay inay ku jireen wadada shucaaca shucaaca ka badan meelaha kale".
