Menene Mai Gano Scintillation Yayi?Ƙa'idar Aiki Mai Gano Scintillation

A scintillation detectorna'ura ce da ake amfani da ita don ganowa da auna ionizing radiation kamar gamma rays da X-rays.

Ka'ida 1

Ka'idar aiki ta ascintillation detectorza a iya taƙaita shi kamar haka:

1. Scintillation kayan: Mai ganowa ya ƙunshi lu'ulu'u na scintillation ko scintillator na ruwa.Waɗannan kayan suna da ikon fitar da haske lokacin farin ciki ta hanyar ionizing radiation.

2. Radiation na faruwa: Lokacin da ionizing radiation yana hulɗa tare da kayan scintillation, yana tura wasu ƙarfinsa zuwa harsashi na lantarki na atom a cikin kayan.

3. Haɗawa da haɓakawa: Ƙarfin da aka canjawa wuri zuwa kwandon lantarki yana haifar da atom ko kwayoyin halitta a cikin kayan scintillation don jin dadi.Ƙwayoyin zarra ko kwayoyin da ke cike da farin ciki daga nan sai su dawo da sauri zuwa yanayinsu, suna fitar da kuzarin da ya wuce gona da iri ta hanyar photons.

4. Ƙirƙirar haske: Ana fitar da hotunan photon da aka saki a kowane bangare, suna haifar da walƙiya na haske a cikin kayan scintillation.

5. Gano haske: Daga nan sai na'urar gano hoton da aka fitar, kamar bututun daukar hoto (PMT) ko bututun daukar hoto na silicon (SiPM).Waɗannan na'urori suna canza photon masu shigowa zuwa siginar lantarki.

6. Ƙwaƙwalwar sigina: Ana ƙara siginar lantarki da mai daukar hoto ya haifar don ƙara ƙarfinsa.

7. Sarrafa sigina da bincike: Ana sarrafa siginar da aka haɓaka kuma ana bincikar siginar lantarki ta hanyoyin lantarki.Wannan na iya haɗawa da canza siginar analog zuwa siginar dijital, ƙidayar adadin photon da aka gano, auna ƙarfinsu da rikodin bayanai.

Ta hanyar auna ƙarfi da tsawon lokacin walƙiya da ascintillation detector, za'a iya ƙayyade halayen halayen da suka faru na radiation, kamar ƙarfinsa, ƙarfinsa, da lokacin isowa.Ana iya amfani da wannan bayanin don aikace-aikace iri-iri a cikin hoton likitanci, cibiyoyin makamashin nukiliya, kula da muhalli, da ƙari.
