Los ntawm kev sib tsoo, nws pom tias uranium ntsev spontaneously emit ib tug nkag mus rau hluav taws xobuas tuaj yeem sau npe rau ntawm daim duab thaij duab. Cov kev tshawb fawb ntxiv tau ua kom pom tseeb tias qhov hluav taws xob no yog ib yam tshiab thiab tsis yog X-ray hluav taws xob: nws tau pom qhov tshwm sim tshiab, xov tooj cua.
xov tooj cua nrhiav tau li cas?
Lub Peb Hlis 1, 1896: Henri Becquerel Discovers Radioactivity. Nyob rau hauv ib qho ntawm qhov zoo tshaj plaws kev tshawb nrhiav pom nyob rau hauv keeb kwm ntawm physics, nyob rau hauv ib tug overcast hnub nyob rau hauv lub peb hlis ntuj 1896, Fabkis physicist Henri Becquerel qhib ib tug tub rau khoom thiab nrhiav tau spontaneous radioactivity.
Leej twg nrhiav tau xov tooj cua thawj zaug?
Txawm hais tias nws yog Henri Becquerel uas nrhiav tau qhov tshwm sim, nws yog nws tus kws kho mob tus tub ntxhais kawm, Marie Curie, uas tau hu nws: xov tooj cua.
Becquerel nrhiav tau xov tooj cua quizlet li cas?
Tshawb nrhiav xov tooj cua hauv xyoo 1896 nws xav tias X-ray tau tawm nrog phosphorescence. Muab tso rau hauv cov pob zeb uas muaj cov poov tshuaj uranyl sulfate rau saum lub phaj thaij duab qhwv hauv daim ntaub dub. Tom qab ntawd nws muab lub phaj qhwv thiab cov pob zeb tawm sab nraud kom pom cov hnub ci.
leej twg yog leej txiv ntawm xov tooj cua?
Henri Becquerel, nyob rau hauv tag nrho Antoine-Henri Becquerel, (yug Lub Kaum Ob Hlis 15, 1852, Paris, Fabkis-tuag Lub Yim Hli 25, 1908, Le Croisic), Fabkis tus kws kho mob uas tshawb pom cov xov tooj cualos ntawm nws cov kev tshawb fawb ntawm uranium thiab lwm yam khoom. Nyob rau hauv 1903 nws tau muab lub Nobel nqi zog rau Physics nrog Pierre thiab Marie Curie.
