ʻO ka wai hoʻoheheʻe nuklea ≠ ka wai hoʻoheheʻe nuklea
ʻO ka wai ʻōpala nuklea e pili ana i ka wai ʻino i hoʻokuʻu ʻia mai nā mea kanu nuklea.ʻO ka wai ʻōpala nuklea ka nui o nā mea hana nui a me nā lako wai hoʻoheheʻe wai, ka wai hoʻokuʻu reactor, ʻoi aku ka nui o ka wai radioactive haʻahaʻa.ʻO ka wai ʻōpala nuklea ʻOiai ma hope o ka mālama ʻana i ka wai ʻōpala nuklea, aia pū kekahi, carbon 14, drill 60, 90 a me nā mea paʻakikī ʻē aʻe e wehe loa i nā koena mea radioactive.ʻOi aku ka pōʻino o ka wai i hoʻopōʻino ʻia, a ua hui pū ʻo Iapana i nā mea ʻelua.
ʻEhia ka hopena o ka wai i hoʻohaumia ʻia e Fukushima?
Wahi a ka nānā mua ʻana o ka ulia nuklea Fukushima, ma hope o ke komo ʻana o ka wai i hoʻohaumia ʻia i ka moana, lawe mua ʻia e nā au kai, a e laha i nā moana like ʻole, ma kahi o 240 mau lā ma hope o ke komo ʻana i ko kākou kai.
No ke ola moana paha, a no ke kanaka paha, he mea ino loa ia.Ke hoʻohaumia ʻia me kēia mau mea haumia radioactive, hiki iā ia ke komo pololei i loko o nā mea kanu a me nā holoholona, e hoʻololi ai i ke kaʻina genetic, e hoʻoulu ai i nā maʻi koʻikoʻi, e like me ke kanesa a pēlā aku.I ka manawa like, nui loa kona hopena i ka hanauna e hiki mai ana, ʻo ka hopena intuitive ʻo ia nā deformities koʻikoʻi a me nā maʻi genetic o ka hanauna hou.
Pehea e ʻike ai i ka radiation a puni?
ʻOiai ʻaʻole hiki ke ʻike ʻia a hoʻopā ʻia ka pāhawewe nuklea, akā ʻoiaʻiʻo i ka lewa, ka lepo, ka wai kai ma ka wahi waena, inā ʻoi aku ka nui o ka radiation nuklea ma mua o ka palekana, e hōʻeha ia i ke kino o ke kanaka, makemake e ʻike i ka nuklea. ʻO ka radiation, pono ʻoe e hoʻohana i nā mea hana ʻoihana: nuklea radiation detector.
Pehea ka hana ʻana o kahi mea hana hoʻoheheʻe nuklea?
ʻike ʻia ka mea hoʻoheheʻe nuklea ma ke ʻano he mea ʻike nukle.He mea hana ia no ka ʻike ʻana i ka radiation.
ʻO ka ʻāpana koʻikoʻi o ka mea hana ʻike radiation nuklea ka sensor.Hoʻokumu ʻia ka mea ʻike uila nuklea ma ka absorption, backscattering a i ʻole ionizing excitation o ka mea i ana ʻia.Hāʻawi nā isotopes radioactive i nā ʻāpana (a i ʻole nā kukui) me ka nui o ka ikehu i ka wā palaho, me ka alpha, beta, gamma, a me nā kukuna neutron.ʻO kāna hana ʻo ka hoʻololi ʻana i nā ʻike kino, kemika a me nā ʻike ʻē aʻe e pono e ʻike ʻia i mau hōʻailona uila hiki ke ana, a laila hāʻawi iā lākou i ka chip no ka helu ʻana.
He aha nā ʻāpana e pono ai no nā mea ʻike uila nuklea?
1. ʻO ka chip receiver kekahi o nā mea koʻikoʻi koʻikoʻi o ka ʻike uila nuklea;Eia 7 mau pahu hoʻokipa ADI
