Zowunikira ma radiation ya nyukiliya zimafunikira chipangizochi.

Madzi owonongeka a nyukiliya ≠ zimbudzi za nyukiliya 

Madzi otayira a nyukiliya nthawi zambiri amatanthauza madzi otayira otuluka m'mafakitale opangira magetsi a nyukiliya.Madzi otayira a nyukiliya amaphatikizanso zida zazikulu ndi zida zothandizira madzi okhetsera, madzi otulutsa riyakitala, makamaka amadzi otayira otsika komanso apakatikati.Madzi otayira a nyukiliya Ngakhale pambuyo pa "kusefa" kwa madzi a nyukiliya, mulinso, carbon 14, drill 60, 90 ndi zina zovuta kuchotsa zotsalira za radioactive.Madzi owonongeka ndi nyukiliya ndi owopsa kwambiri, ndipo Japan ikuphatikiza ziwirizi.

Kodi madzi oipa a Fukushima atikhudza bwanji?

Malinga ndi kuwunika koyambirira kwa ngozi ya nyukiliya ya Fukushima, madzi oipitsidwa ndi nyukiliya atalowa m'malo a Marine, amayamba kunyamulidwa ndi mafunde a m'nyanja, ndipo adzafalikira kunyanja zosiyanasiyana, pafupifupi masiku 240 atalowa m'nyanja yathu.

Kaya ndi zamoyo Zam'madzi, kapena za anthu, ndizovulaza kwambiri.Ikayipitsidwa ndi zowononga zotulutsa ma radio, imatha kulowa mwachindunji mkati mwazomera ndi nyama, zomwe zimapangitsa kusintha kwa ma genetic, zomwe zimayambitsa matenda oopsa, monga khansa ndi zina zotero.Panthawi imodzimodziyo, zotsatira zake pa m'badwo wotsatira zimakhalanso zazikulu kwambiri, zomwe zimakhudzidwa kwambiri ndizowonongeka kwakukulu ndi matenda amtundu wa m'badwo watsopano.

Momwe mungadziwire ma radiation mozungulira?

Ngakhale cheza nyukiliya sangawoneke ndi kukhudza, koma kwenikweni mu mlengalenga, nthaka, madzi a m'nyanja m'malo sing'anga, ngati nyukiliya poizoniyu mtengo kuposa osiyanasiyana otetezeka, zidzachititsa kuvulaza thupi la munthu, ndikufuna kuona nyukiliya. radiation, muyenera kugwiritsa ntchito zida akatswiri: nyukiliya radiation chowunikira.

Kodi chida cha nyukiliya chimagwira ntchito bwanji?

nyukiliya radiation detector imadziwikanso kuti nyukiliya yozindikira chinthu.Ndi chipangizo chodziwira ma radiation.

Chigawo chachikulu cha chida chodziwira ma radiation ya nyukiliya ndi sensor.Mphamvu yamagetsi ya nyukiliya imatengera kuyamwa, kubweza kapena ionizing chisangalalo cha chinthu choyezedwa.Ma isotopu a radioactive amatulutsa tinthu ting'onoting'ono (kapena cheza) chokhala ndi mphamvu inayake pakawola, kuphatikiza kuwala kwa alpha, beta, gamma, ndi neutroni.Ntchito yake ndikusintha zidziwitso zosiyanasiyana zakuthupi, zamankhwala ndi zina zomwe zimafunikira kuzindikirika kukhala ma siginecha amagetsi oyezeka, ndikuzipereka ku chip kuti ziwerengedwe.

Ndi tchipisi ziti zomwe zimafunikira pa zowunikira ma radiation ya nyukiliya?

1. Chip cholandirira ndi chimodzi mwazinthu zofunika kwambiri za chowunikira chowunikira cha nyukiliya;Nawa tchipisi 7 zolandila ADI

Njira yolandirira chowunikira cha radiation (a, B, X-ray resolution):

Mtengo wa AD5160

Magawo azinthu: 256-Position SPI-Compatible Digital Potentiometer

Zinthu zazikulu ndi zabwino zake: Kuwongolera mawonekedwe a SPI, potentiometer ya digito, kuwongolera kolondola kwa kupindula kwa amplifier.

Zofunikira zazikulu ndi zopindulitsa: Kutsika pang'ono, phokoso lotsika, kuchuluka kwamagetsi olowetsamo, kumapereka gwero lolozera ma ADC olondola.

Njira yowonera ma radiation yothamanga kwambiri (y ray, neutron resolution):

Mtengo wa LTC6268-10

Zogulitsa: 4GHz Ultra-Low Bias Current FET Input Op Amp

Zofunikira zazikulu ndi zabwino: Ultra-wideband, kukondera kochepa, phokoso lotsika, ngati pre-op amp.

2. Malingana ngati pali njira yogwiritsira ntchito magetsi, ndikofunikira kuchita kasamalidwe ka mphamvu, ndipo chipangizo chamagetsi chimatha kuonetsetsa kuti chipangizochi chikugwira ntchito bwino;Nawa zida zitatu za ADI zogawana:
