Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mumatanho okupedzisira epurogiramu yokuedza kubhururuka, kuedza kupopota kwakaratidza kuti mapapiro acho aizununguka mumamiriro ezvinhu akati. Dambudziko iri rakagadziriswa nokuita kuti zvimwe zvikamu zvemapapiro zvive zvishoma kuomarara. Zvisinei, chinetso chakakomba zvikuru chokudengenyeka kwechimbichimbi chakagadziriswa bedzi nokuisa uranium yakaderedzwa sechinhu chinorema muinjini dzomukati dzemotokari dzokutanga dze747s.
