Tus Tshiab ACGIH 222nm UV Tshaj Tawm TLVs rau tib neeg raug

Cov kev tshawb fawb tshiab tau ua pov thawj tias 222nm UVC muaj kev nyab xeeb rau tib neeg cov tawv nqaij, tab sis raws li tus qauv photobiosafety IEC / EN 62471, qhov siab tshaj plaws tso cai UVC raug ntawm 222nm yog 22mJ / cm², zoo ib yam nrog 254nm. Cov ntaub ntawv tseem tsis tau hloov kho.

Tsis ntev los no, ACGIH tau tshaj tawm tsab ntawv tshaj tawm tshiab ntawm 2022 qhov pib txwv qhov tseem ceeb (TLVs) thiab cov khoom siv hluav taws xob (BEIs). Hauv tsab ntawv tshaj tawm no, los ntawm nplooj 152 txog 162 peb tuaj yeem pom TLVs tshiab rau UV hluav taws xob. Siv cov qauv sib raug thiab raws li qhov hnyav spectral coefficient, peb tuaj yeem tau txais TLV rau 254nm ntawm 6 mJ / cm², thiab TLV rau 222nm tau nce los ntawm 22mJ / cm² mus rau 478 mJ / cm², nyob rau hauv rooj plaub ntawm daim tawv nqaij raug, thiab 160mJ / cm² rau qhov muag pom.

Cov kev cai hais txog cov txheej txheem photobiosafety ntawm 222nm UVC yuav tsum tau hloov kho sai sai nrog cov lus pom zoo tshiab ntawm ACGIH.
