E wuru ya na ngwụcha afọ 1940, Mayak bụ otu n'ime ụlọ ọrụ nuklia a ma ama na Russia. Gọọmentị zoro ụlọ ọrụ ahụ ruo n'afọ 1990. Mgbè ónyé isi ala Russia Boris Yeltsin bịanyere aka na iwu afọ 1992 na-emeghe mpaghara ahụ, ndị ọkà mmụta sayensị ọdịda anyanwụ nwèrè ike ịnweta. A na-eme atụmatụ na ihe dị n'ala ọdọ mmiri ahụ nwèrè ihe fọrọ nke nta ka ọ bụrụ ihe niile dị elu nke radiation radiation na omimi nke ihe dịka feet irí na otu (3.4 m).
N'afọ 1994, akụkọ kpughere na nde cubic mita isé nke mmiri mmetọ esila n'Ọdọ Mmiri Karachay kwaga, ma na-agbasa n'ebe ndịda na n'ebe ugwu na mita iri asatọ kwà afọ, "na-eyi egwu ịbanye n'ime mmiri na osimiri".[3] Ndị dere ya kwetara na "ihe ize ndụ ndị e chepụtara echepụta ghọrọ ihe ndị méré eme".

Mgbè ụkọ mmiri ozuzo mèrè ka mmiri daa, na-ekpughe ụrọ emetọ, nke ifufe na-ebugharị, na-emetọwanye mpaghara ndị gbárá ya gburugburu, e kpebiri iji mejupụta ọdọ mmiri ahụ kpamkpam.[5] Ka ọ na-erule n'ọnwa Disemba afọ 2016, ọnọdụ ọdọ mmiri ahụ jupụtara kpamkpam, na-eji blọk simenti pụrụ iche, nkume, na unyi. A rụchara ya kpamkpam n'ọnwa Nọvemba 2015, mgbè ahụ nyochara ya tupu etinye akwa ikpeazụ nke nkume na unyi. Nnyocha data gosipụtara "ebelata doro ányá nke ntinye nke radionuclides n'elu" mgbè ọnwa iri gasịrị.[6] A na-atụ anya na a ga-etinye usoro nlekota nke were ọtụtụ iri afọ màkà mmiri dị n'okpuru ala n'oge na-adịghị ányá.[6]
Osimiri Techa, nke na-enye mmiri na mpaghara ndị dị nso, emetọla, ihe dị ka pasenti iri isii na ise nke ndị bi n'ógbè ahụ dara ọrịa radiation.
