Wewe huu upuzi wote unaleta hapa ukisema kenya ni weak weka evidence ...idiot

Idiot mwenyewe. Huoni Al Shabab wanavyowajambisha. Yaani wanamgambo tu wenye mapanga na marungu wanawafanya mjikojolee. Kenya ni weak sana
Evidence hii hapa chini

nuclear plant sijui inaanza lini kweli kwani inataka pesa kibao lakini inatakiwa imalizike 2027 in readiness for vision 2030...na sio lazima uwe msomi ili utumie akili...

wajenge tu ili mradi isiwe ni silaha. maana sometimes wakenya hawaaminik wakipata nucleur bombs wanaweza kujimaliza wenyewe kwa wenyewe

Sasa hayo yote unaongelea uranium.

There are four main radioactive isotopes that have lasted as long as the Earth:

  • Uranium-239 (over 99% of all uranium) with a half-life of 4.5 billion years
  • Uranium-235 (less than 1% of all uranium) with a half-life of 700 million years
  • Thorium-232 (100% of Thorium) with a half-life of 14 billion years
  • Potassium-40 (0.01% of all potassium) with a half-life of 1.28 billion years. Since there is so little of this isotope compared to stable Potassium-39 and 41, potassium minerals are not considered radioactive (although they all are, to a tiny degree).
That means that essentially all radioactive minerals contain either uranium or thorium. The Rare Earth Elements typically include a percentage of uranium and/or thorium as trace elements, rendering many of them slightly radioactive. Note that both uranium and thorium have decay chains involving many short-lived isotopes (they consequently emit much more radiation than a simple isotope such as tritium), but these are present in tiny traces and typically don't exist long enough to become concentrated and form minerals.

Soma hapa upate elimu kidogo:-

Fala nimesema Niobium ..najua kufusu uranium na its half lifes

Niobium inatokana na Uranium. Kama ulisoma ulikuwa unakariri. Rudi shule wewe.
Halafu rudi kusoma hapa:-

Umetaja Niobium wapi hapo? Its not radioactive as such kama uranium ...some of its isotopes are but its not used for its rafioactive porposes

Soma document yote wewe niliyokupatia. Acha uzembe

Wewe unapewa document usome badala ya kusoma unakuja ku comment tu hapa.

Soma sasa hapa chini nimekuwekea hapa:-

There are other relatively common radioactive nuclides: Radium-226 and Radon-222 are both produced during the decay of Uranium. Radon is considered the most hazardous, because as a gas we breathe it into our lungs where it can attach until it decays. Luckily, Radon only has a 4-day half-life, which limits the build-up in a basement or from a concrete wall. Unluckily, Radon only has a 4-day half-life, which means it is extremely radioactive.

Another well-known radioactive isotope is Carbon-14, produced as a measurable trace by cosmic rays acting on atmospheric CO2, and with a half-life of 5732 years. Since it is carbon, it is readily incorporated into all living things. Indeed, our bodies are naturally radioactive, to a degree, from all of these sources (Potassium-40 contributes the most, then Carbon-14, then Uranium and its decay products).

Minerals containing Uranium (radioactivity is proportional to the fraction of uranium, and alpha particles are primarily emitted from the surface):

 
Kenya iko mbali sana, 2016 tulipewa aproval by UN atomic agency , tushatunga Sheri's na kola kitu hadi wanafunzi wa nuclear science pale UON wako karibu ku graduate, UoN ilishakua accredited ku handle nuclear material sio kama nyinyi bado ni Kama mnasomea engeneering kavu

 
Sasa wewe unaongelea 2016 wakati TZ ipo na Aproval toka miaka mingi sana. Kuna vitu huvijui. Uliza tukusaidie. Utachekwa wewe. Or ask your government.

Hatuongei approval ya kujenga research facility, tunaongea approval ya kujenga nuclear plant, tanzania bado iko nyuna kama kawa... Lakini vile mnapenda kujidanganya utaskia mtu kama wewe bado anashabikia kishindana pale kenya imefika ..... Vitu vingine hata hauhitaji kuangalia mbali, kama tz au nchi yoyote hapa EA ingekua most likely kujenga nuclear in this decade, conference kama hio ya nuclear inayofanyika KICC ingefanywa ndani ya hio nchi iliyopiga hatua zaidi
 
Weka hapa hito link tuione. Siyo kutuwekea picha.
