Cobalt foob pob raws li ib tug riam phom uas huab hwm coj puas tsuaj.

Cobalt foob pob yog ib tug theoretical kev hloov kho ntawm riam phom uas huab hwm coj kev puas tsuaj, uas ua rau yus siab degrees ntawm tej kab mob sib kis thiab kab mob sib kis ntawm cov cheeb tsam nrog ib tus me quab yuam ntawm cov tawg. Cobalt foob pob yog hais txog moj riam phom, uas raws li ib tug tawm tshaj yuav yog tus ionizing tawg. Nyob rau tib lub sij hawm, vim hais tias ntawm tus kwv tij tsis muaj zog ntawm lub tawg, yuav luag tag nrho infrastructure, vaj tse, lug thiab vaj tse nyob twj ywm lawm.

Cobalt foob pob - ib tug nuclear riam phom, lub plhaub uas yog tsis ua los ntawm uranium-238 thiab cobalt-59 los ntawm. Thaum av tshwm sim irradiation plhaub haib neutron flux, uas tau nyob rau hauv transmutation ntawm cobalt-59, cobalt-60 isotope. Nws ib nrab-lub neej yog ib tug me ntsis tshaj 5 xyoos. Raws li ib tug tshwm sim, lub beta-lwj ntawm no nuclide yog tsim ntawm npib tsib xee-60 nyob rau hauv lub active lub xeev, uas tom qab ib co sij hawm mus rau hauv av.

cobalt-60 kev ua si Uas ib gram kwv yees li 1130 Ci. Rau siab mob rau lub qhov tag nrho lub ntiaj teb nto tawg theem grams / square kilometer cobalt-60 yuav tsum tau hais txog 510 tons. Nyob rau hauv dav dav, lub tawg ntawm xws li ib tug pob yuav paug cov cheeb tsam ze li ntawm 50 xyoo. Tej ntev ua ke tawm me ntsis sij hawm los mus ciaj sia mob pejxeem, txawm nyob rau hauv lub bunkers.

Nws yog ntseeg hais tias cov cobalt foob pob yeej tsis tsim, yog li ntawd nws tsis tsim nyog nyob rau hauv qhov kev pab tsis muaj lub teb chaws. Ib tug me me npaum li cas ntawm qhov no caij tau siv nyob rau hauv ib tug ntawm cov UK sim ib tug nuclear riam phom rau radiochemical tag. Biggest obstacles rau tsim xws li ib tug munition technically tsis muaj, tab sis ib tug high degree ntawm kis ntawm tus struts thiab nws ntev tsis pub muaj kev nyab xeeb kev nws. Tej mos txwv yeej tsis ua thiab twb tsis kuaj vim yog cov txaus ntshai thaum uas siv los tawm tsam lawv tus kheej.

Qhov tseem txaus ntshai txoj kev siv ntawm ib tug cobalt foob pob yog nws tawg nyob rau high school altitude, ib tug me ntsis deb ntawm lub chaw uas zoo heev ntawm tus yeeb ncuab, nyob ntawm seb cov huab cua puag. Nyob rau hauv cov ntaub ntawv no, lub hom phiaj yog kom tau hla dhau lub teb chaws ntawm cov yeeb ncuab fallout uas yuav theoretically rhuav tshem tag nrho lub neej nyob rau nws.

Cov heev lub tswv yim ntawm no lub foob pob yog invented los ntawm physicist Leo Szilard, uas tau ua lub assumption tias cov arsenal ntawm cobalt bombs muaj peev xwm ntawm kev rhuav tseg tag nrho ntawm lub ntiaj teb no tus pej xeem. Cobalt tau raug xaiv los vim lub fact tias cov neutron kom nws muab ib tug heev muaj zog thiab kav ntev tej kab mob sib kis. Nws yog tej zaum yuav siv lwm yam hais uas tsim ntau isotopes nrog ntev ib nrab-lub neej los mus tsim tej mos txwv, tab sis lawv cov kev ua no kom meej meej tsis txaus. Tseem muaj short-lived isotopes piv nrog cobalt-60, xws li sodium-24, zinc-65 thiab kub-198, tab sis vim lub kuj sai cev qhuav dej ntawm lawv cov kev faib ua feem ntawm cov pejxeem yuav muaj sia nyob cov kab cheeb tsam nyob rau hauv silos.

Sakharov, uas twb xub tsim lub hydrogen foob pob, twb tseem muab kev koom tes nyob rau hauv theoretical uas thorium, cobalt tej tawg hem thiab hu ua nws "toadstool-tus tshwj ntxim". Txawm lub creation ntawm lub hydrogen foob pob thiab nws xeem tsis tau ua tus paub txog ntawm "flattering" epithets. Cobalt foob pob yuav suav hais tias ob qho tag nrho ib neutron thiab radiology, qhov thiaj li hu ua "dirty" riam phom.
