Kula da ragewa na Beta

BAM (BET) wata hanyar saka idanu ce ta iska wacce ke amfani da sinadarin radiation na beta ta hanyar ƙwayoyin da aka cire daga iska. Hanyar taro ba da damar gano PM da PM.5, waɗanda yawancin hukumomin kula da gurɓataccen iska ke sa ido. Babban ka'idar ta dogara ne akan wani nau'in dokar Bouguer (Lambert-Beer): adadin da ke rage kwararar radiation beta (electrons) ta hanyar abu mai ƙarfi ya dogara da nauyinsa kuma ba akan wani fasalin ba (kamar yawa, sinadarin sinadarai ko wasu kayan gani ko lantarki) na wannan al'amari. Don haka, ana fitar da iska daga waje na gani ganowa ta hanyar "marasa iyaka" (tsalle-tsalle) ribbon da aka yi daga wasu kayan tacewa don a tattara barbashi a ciki. Akwai tushe guda biyu na radiation beta da aka sanya daya kafin da daya bayan yankin inda iska ke wucewa ta cikin layin da ke barin barbashi a ciki; kuma akwai masu ganowa guda biyu a gefen layin, suna fuskantar masu ganowa. Ƙarfin tushen da ƙwarewar masu ganowa iri ɗaya ne (ko gyara tare da teburin binciken da ya dace), ƙarfin hasken beta da ɗayan masu ganowa ya gano an kwatanta shi da na ɗayan. Ta haka ne mutum zai iya cire yawan nauyin da ribbon ya samu bayan an fallasa shi ga iskar iska; sanin saurin zubar da ruwa, ana iya tantance ainihin ma'aunin ma'auni a cikin iska.

Irin wannan hanyar ta wanzu, inda maimakon kwararar ƙwayoyin beta ana amfani da sa ido na X-ray Fluorescence Spectroscopic a kowane bangare na hulɗar iska tare da layin. Wannan yana ba da damar samun ba kawai ma'auni na ma'aunin ƙwayoyin ba, har ma da gano matsakaicin sinadarin su (aikin fasaha don potassium da abubuwa masu nauyi fiye da shi).
