Nekusimukira kuri kuita sainzi neruzivo rwemichina uye kusimukira kweruzivo rwekurapa, mikana yekuti vanhu vaonekwe maX-rays pavanoenda kuchipatara wawedzerawo zvikuru.Wese munhu anoziva kuti chipfuva X-rays, CT, color ultrasound uye X-ray michina inogona emit X-rays kupinda mumuviri wemunhu kuona chirwere.Vanoziva zvakare kuti X-rays inoburitsa mwaranzi, asi vangani vanhu vanonyatsonzwisisa michina yeX-ray.Zvakadini nemwaranzi inobudiswa?
Kutanga, maX-rays ari sei mune imweX-ray muchinakugadzirwa?Mamiriro ezvinhu anodiwa pakugadzirwa kwe-X-rays anoshandiswa mukurapa ndeaya anotevera: 1. X-ray tube: vacuum glass tube ine ma electrodes maviri, cathode uye anode;2. Tungsten plate: metal tungsten ine nhamba yeatomu yakakwirira inogona kushandiswa kugadzira machubhu eX-ray Anode ndiyo inotarisirwa kugamuchira electron bombardment;3. Ma electrons anofamba nekumhanya kukuru: shandisa high voltage kumagumo ese eX-ray chubhu kuita kuti maerekitironi afambe nekumhanya kukuru.Specialized transformers kusimudzira mhenyu voltage kune inodiwa yakakwirira voltage.Mushure mekunge tungsten plate yarohwa nemaerekitironi achifamba nekumhanya kukuru, maatomu etungsten anogona kuiswa maerekitironi kuita maX-ray.
Chechipiri, chii chinonzi X-ray iyi, uye nei ichigona kushandiswa kuona mamiriro mushure mekupinda mumuviri wemunhu?Izvi zvese nekuda kwemaitiro eX-rays, ane zvinhu zvitatu zvikuru:
1. Kupinza: Kupinza kunoreva kugona kweX-rays kupfuura nemuchinhu pasina kubatwa.X-rays inogona kupinda muzvinhu izvo chiedzawo zvacho chinooneka chisingagoni.Chiedza chinooneka chine urefu hwakareba, uye maphoton ane simba shoma.Kana ichirova chinhu, chikamu chacho chinoratidzwa, chizhinji chacho chinotorwa nechinhu, uye hachikwanisi kupfuura nechinhu;nepo X-rays isiri, nekuda kwehupfupi hwavevelength, simba Painopenya pazvinhu, chikamu chete chinotorwa nechinhu, uye yakawanda yacho inopfuudzwa kuburikidza neatomu gap, ichiratidza simba rakasimba rinopinda.Kugona kweX-rays kupinda mukati mechinhu kune hukama nesimba reX-ray photons.Kupfupika kwewavelength yeX-rays, ndiko kukura kwesimba remaphoton uye kusimba kwesimba rinopinda.Simba rinopinda reX-rays rinoenderanawo nekuwanda kwezvinhu.Iyo denser zvinhu inotora yakawanda X-rays uye inotumira zvishoma;iyo denser material inotora zvishoma uye inotumira yakawanda.Kushandisa iyi pfuma yekusiyanisa kunyura, zvinyoro zvinyoro zvakaita semapfupa, mhasuru, uye mafuta ane densities akasiyana anogona kusiyaniswa.Iyi ndiyo hwaro hwemuviri hweX-ray fluoroscopy uye kutora mafoto.
2. Ionization: Kana chinhu chikavhenekerwa neX-ray, maerekitironi eextranuclear anobviswa kubva paatomu orbit.Mhedzisiro iyi inonzi ionization.Mukuita kwephotoelectric effect uye kuparadzira, maitiro ayo maphotoelectrons uye recoil maerekitironi anoparadzaniswa kubva kumaatomu avo anonzi primary ionization.Aya maerekitironi kana marecoil maerekitironi anodhumhana nemamwe maatomu paanenge achifamba, zvekuti maerekitironi anobva pamaatomu anorohwa anonzi secondary ionization.muzvakaoma uye zvinwiwa.Iyo ionized yakanaka uye yakaipa ions ichabatana nekukurumidza uye haisi nyore kuunganidza.Nekudaro, iyo ionized charge mugasi iri nyore kuunganidza, uye huwandu hweiyo ionized charge inogona kushandiswa kuona huwandu hweX-ray exposure: X-ray yekuyera zviridzwa zvinogadzirwa zvichibva pane iyi musimboti.Nekuda kweionization, magasi anogona kuitisa magetsi;zvimwe zvinhu zvinogona kusangana nemakemikari;zvakasiyana-siyana zvipenyu zvinokonzerwa nehupenyu zvinogona kukonzerwa muzvisikwa.Ionization ndiyo hwaro hweX-ray kukuvara uye kurapwa.
3. Fluorescence: Nekuda kwehupfupi hurefu hweX-rays, hazvionekwe.Zvisinei, kana yatungidzirwa kune mamwe macommunication akadai sephosphorus, platinum cyanide, zinc cadmium sulfide, calcium tungstate, zvichingodaro, maatomu anenge ari muchiitiko chekufara nekuda kweionization kana kufara, uye maatomu anodzokera pasi mukuita. , nokuda kwekuchinja kwesimba remagetsi evalence electrons.Inoburitsa inooneka kana ultraviolet chiedza, inova fluorescence.Mhedzisiro yeX-rays inokonzera zvinhu ku fluoresce inonzi fluorescence.Kusimba kwefluorescence kunoenderana nehuwandu hweX-rays.Ichi chiitiko ndicho chikonzero chekushandiswa kweX-rays kune fluoroscopy.Mune X-ray yekuongorora basa, rudzi urwu rwefluorescence rinogona kushandiswa kugadzira fluorescent skrini, intensifying screen, yekuisa skrini mumufananidzo intensifier uye zvichingodaro.Chidzitiro chefluorescent chinoshandiswa kuona mifananidzo yeX-rays ichipfuura nemunyama yemunhu panguva yefluoroscopy, uye inosimbisa skrini inoshandiswa kuwedzera kunzwisiswa kwefirimu panguva yekutora mifananidzo.Izvo zviri pamusoro ndeyesumo yakajairika yeX-rays.
