Alpha shucaaca

Mid ka mid ah nooca shucaaca nuclear, taasoo khuseysaa dhammaan hadda loo yaqaan in noocyada sayniska iyo noocyada kala duwan ee hirarka, qayb ka, waa shucaaca Alfa. Isha of this ifafaale u dhaqmo sida a (laaluusheen) shucaaca dabiici ah ama aan dabiici ahayn abuuray. Nooca shucaaca la initialized iyo soo baxa degna yeedhay shucaaca dabiiciga ah iyo "xubnaha" ay - xuduntii ah ee isgaarsiinta ruxanaya gudaha u dhexeeya Qurub hoose xuduntii. Tusaale ahaan, ka nuclei qaybaha shucaaca sida sida uranium ama radium-235 degna dhaadheer kartaa Alfa, beta iyo Qurub gamma. Iyadoo la raacayo, waxaa jira iyo noocyada shucaaca nuclear: shucaaca Alfa, shucaaca beta iyo gamma-shucaaca.

Daraasado ayaa muujiyey Alfa in qayb ka yihiin xad aan dhib lahayn in ay jidhka bini'aadamka maxaa yeelay, way isagoo xawaare ku filan sare, si kastaba ha ahaatee, waxay leeyihiin awood cabaar yar. Tani ma la odhan karaa noocyada kale ee Qurub - positrons, electrons, Qurub beta, kaas oo ay leeyihiin iman kara a tamarta badan, sidaa darteed, cabaar ka badan. Sida ee hirka sare rays, Qurub gamma, awood u leeyihiin in lays aad u sarreeya iyo naf-gooyada ah.

Marka la soo koobo, shucaaca Alfa ah - nooc ka mid ah shucaaca ionizing, taas oo ah il lama filaan ah ama toos ah qayb ka wanaagsan oo lagu eedeeyay isagoo xawaare sare oo ka iman kara tamarta la taaban karo.

Iyada oo ku saleysan hadda la heli karo maalin aqoonta berrinkii nuclear tamarta, ugu weyn ilaha shucaaca Alfa waa isotopes radioactive ee walxaha in ay leeyihiin burburkii hantida, daciifnimada ah bonds qaaradda iyo dhaadheer qurubyada alfa ee geedi socodka ee bololka this.

Sida hore u soo sheegnay, feature ugu muhiimsan ee shucaaca Alfa, oo iyaga la kala saaro noocyada kale ee shucaaca nuclear, waa awoodda yar cabaar. saamaynta waxa lagu sharaxay by xaqiiqada ah in qayb ka ah waxay leeyihiin xawaare sare, oo sidaas daraaddeed jid ionization ay si dhakhso ah gudbaan. Jidka, "soo socda" qurubyada alfa yihiin awood u abuuraya tiro badan oo udhigo in ay u sameeyaan, oo iyana, cufnaanta ah ionization sare.

Joogitaanka cufnaanta ah ionization weyn go'aamisa waxtarka noolaha ee shucaaca Alfa, taas oo min toban ah oo ku saabsan ka sii badan tahay in lagu arkay iyadoo shucaaca X-ray. tallaabo noocan oo kale ah ee u shaqeeyo aadanaha waxaa loo muujiyey in xaqiiqda ah in ay sabab u tahay waddada xawaaraha sare ee ay dusha laga yaabaa inuu dhaco gubasho. Haddii Alfa-qayb u hesho jirka gudihiisa, tusaale ahaan, iyada oo loo marayo afka ama furan daweeyo nabrihii, waxay ka dibna ku faafay jidhka bini'aadamka oo dhan iyadoo la kaashanayo socodka dhiigga. Xaaladdan oo kale waxaa jira cindiga gudaha ah.

saamayn Tani waxay u ogolaaneysaa isticmaalka shucaac Alfa in daawaynta cudurada kala duwan ee nidaamka wax-u therapy Alfa.

dabeecadda Jirka iyo kiimikada ee ifafaale ah ee shucaaca Alfa waa in udhigo ka soo saaray marinka qayb Alfa si dhakhso ah adiga oo isticmaalaya iman kara ay tamar, ka dib markii taas udhigo kuwaas waxaa loo beddelaa ee atamka helium ugu caadiga ah. Sidaas darteed, waxaan la hadli kartaa ee ku saabsan horumarka ee unugyada noolaha ee u shaqeeyo aadanaha falcelinta radiochemical. Dareen-celinta waxay u ogolaadaan isticmaalka shucaac Alfa ujeedooyin caafimaad, sababta oo ah waxa la aasaasay ee koorsada of isotopes - radon, thoron, ayaa muddo gaaban oo uu naftiisa iyo ma keeni kartaa waxyeello ka sii daran in jidhka waafaqsan qiyaasta ammaan aasaasay iyo tallaabooyin taxaddar ah oo kale.

Qaabka ugu muhiimsan ee lagu jiro therapy Alfa ka mid ah qubeyska radon shaqo, codsiga oo ah radioactive Alfa-qaniinaa, meelaha ay saameeyeen ee jirka, isticmaalka biyaha radon, neefsado hawada radon-hodanka ah.

nidaamyada waxay leeyihiin saamayn togan ku saabsan hababka dareemayaasha iyo wadnaha, waxay leeyihiin xanuunka iyo saamaynta anti-bararka.

Si weyn loo yaqaan xarumaha halkaas oo isticmaalka firfircoon ee therapy Alfa ujeeddooyin, daawooyinka waa jiga ee Pyatigorsk, Tskhaltubo, Brambach iyo meelaha kale ee ay jiraan ilo dabiiciga ah ee radon.
