Buɗe tushen – Maganin Gano Radiation Bisa T5L_COF Smart Screen

Kwanan nan, gano ƙarfin radiation a cikin mahalli masu rai da ruwa ya zama batun damuwa.Dangane da wannan buƙatu, DWIN ta ƙirƙira ta musamman kuma ta ƙirƙira wani bayani mai gano radiyo bisa T5L_COF smart screens, kuma ya buɗe ƙirar ƙira don masu amfani su koma ga.

1. Ka'idar ganowa
A Geiger counter kayan aiki ne na kirgawa wanda ke gano musamman ƙarfin ionizing radiation (barbashi, b barbashi, g rays da c rays).Ana amfani da bututu mai cike da iskar gas ko ƙaramin ɗaki azaman bincike.Lokacin da ƙarfin lantarkin da aka yi amfani da shi a kan binciken ya kai ga wani yanki, ray ɗin yana yin ion a cikin bututu don samar da nau'i biyu na ions.A wannan lokacin, ana ƙara girman bugun wutar lantarki kuma ana iya yin rikodin ta na'urar lantarki da aka haɗa.Don haka, ana auna adadin haskoki a kowane lokaci naúrar.A cikin wannan shirin, an zaɓi ma'aunin Geiger don gano ƙarfin radiation na abin da ake nufi.

Bayan na'urar Geiger tana cikin aiki na yau da kullun, lokacin da radiation ta ratsa ta cikin Geiger counter, ana haifar da bugun wutar lantarki daidai gwargwado, wanda za'a iya gano shi ta hanyar katsewar guntuwar T5L na waje, ta haka ne ke samun adadin bugun jini, wanda daga nan ya koma cikin naúrar ma'auni da ake buƙata ta hanyar dabarar lissafi.
Tsammanin cewa lokacin samfurin shine minti 1, ƙimar ma'aunin shine 210 CPM/uSv/hr, lambar bugun jini da aka auna shine M, kuma sashin da aka saba amfani dashi don auna ƙarfin radiation shine uSv/hr, don haka ƙimar da muke buƙatar nunawa shine K. = M/210 uSv/h.
