NTAUB NTAWV GAMMA RAYS

Tsis zoo li optical teeb thiab x - rays , gamma rays tsis tuaj yeem ntes thiab cuam tshuam los ntawm iav. Gamma - ray wavelengths luv heev li lawv ua tau dhau los ntawm qhov chaw nyob rau hauv lub atom ntawm ib tug detector. Gamma - ray detectors feem ntau muaj densely packed crystal blocks.

Yog li ntawd, tib neeg puas tuaj yeem pom X rays thiab gamma rays?

Teb thiab piav qhia: Tib neeg ua tsis tau saib x - rays los yog gamma rays . Tib neeg tsuas muaj peev xwm saib Lub teeb nyob rau hauv lub teeb pom kev ntawm lub electromagnetic spectrum.

Tsis tas li ntawd, gamma rays kuaj tau li cas? Gamma - rays yog kuaj pom los ntawm kev soj ntsuam cov teebmeem uas lawv muaj rau qhov teeb meem. A gamma -ray tuaj yeem ua ob peb yam yooj yim nrog teeb meem. Nws tuaj yeem sib tsoo nrog lub tshuab hluav taws xob thiab tawm mus zoo li lub pob billiard (Compton scatter) lossis nws tuaj yeem thawb lub tshuab hluav taws xob mus rau qib siab zog (photoelectric ionization).

Ntawm no, X rays thiab gamma rays zoo ib yam?

Qhov sib txawv tseem ceeb ntawm gamma rays thiab X - rays yog li cas lawv raug tsim. Gamma rays keeb kwm los ntawm cov txheej txheem daws teeb meem ntawm ib qho kev zoo siab nucleus ntawm radionuclide tom qab nws dhau los ntawm cov hluav taws xob tawg thaum X - rays yog tsim thaum electrons ntaus ib lub hom phiaj los yog thaum electrons rearrange nyob rau hauv ib tug atom.

Peb puas raug gamma rays?

Ntuj tshwm sim gamma - rays muab ib puas-tam sim no, heev low-level qhov chaw nphav rau hluav taws xob , tab sis qhov kev tshawb fawb txog kev kis kab mob loj heev no qhia tias txawm tias nyob rau theem qis heev no muaj kev pheej hmoo me me rau kev noj qab haus huv.
