Buuxi weedha soo socota: Saamaynta shucaaca ee musiibada nukliyeerka ee Fukushima Daiichi waa saamaynta la arkay iyo saadaasha ka dhalatay sii deynta isotope-yada shucaaca ee ka soo baxa Warshadda Nukliyeerka ee Fukushima Daiichi ka dib musiibada
2011 Dhulgariirkii 9.0 ee Tōhoku iyo tsunami (Dhulgariirkii Weyn ee Bariga Japan iyo tsunami ka dhashay). Isotope-yada shucaaca leh ee ka soo baxa weelasha xidhitaanka ee reactors-ka ayaa sabab u ahaa hawo-qaadista si loo yareeyo cadaadiska gaaska, iyo daadinta biyaha qaboojinta ee badda.

Tirada dadka la daadgureeyay ayaa hoos ugu dhacday 49,492 bishii Maarso 2018. Qaddar badan oo walxaha shucaaca ah ee ka dhashay shilka, oo ay ku jiraan iodine-131 iyo caesium-134/137, ayaa tan iyo markii la ogaaday adduunka oo dhan. Heerarka aadka u sarreeya ayaa laga arkay California iyo Badweynta Pacific.
