Ukulahlwa kwe-lumen ephindwe kabini eyomelezwe kwindlela yomoya yemaski yelaryngeal
Uphawu
Inqanaba lokhuseleko: Ihambelana nempahla ekhuselayo yeekhemikhali, Udidi III, Uhlobo lwe-4-B, 5-B kunye nemigangatho ye-6-B Ibonelela ngokhuseleko ngokuchasene nokungcoliswa kwe-radioactive (EN 1073-2)
Ibonelela ngokhuseleko kwiiarhente ezosulelayo (EN 14126) kubandakanya ukuxhathisa ukungena ngegazi kunye nolwelo lomzimba kusetyenziswa igazi elenziweyo (ISO 16603)
Ilaphu kunye ne-seams zibonelela ngomqobo wekhemikhali wokungena kwimichiza ephantsi yoxinaniso lwamanzi asekwe kwimichiza ye-inorganic
Ngokommiselo osuka kwimibutho enoxanduva evela e-China okanye kwamanye amazwe, umenzi akaboneleli ngokhuselo olungenazintsholongwane. Nangona kunjalo, abathengi bakhululekile ukusebenzisa nokuba yi-Gamma okanye i-EtO inyumba.
