Nharo pamusoro payo yeracactivity yakachengetwa kubvira pakagadzirwa. Vamwe vanotsvakurudza vanoti maminitsi makumi matatu ekukurukurirana pafoni anowanzotadzisa uropi basa. Vamwe, zvisinei, vakataura kuwedzera kwekuchenjera pakati peboka rezvipiri. Vamwewo vakabata "kusunungura" kwemakonzo uye vakaona kuti mumakonzo madhigirii epati akadzikira, pamwe nekukwanisa kufamba nenzira yacho. Kunyange zvakadaro, nyanzvi dzinofunga kuti izvi zvose zvinokurudzira. Zvechokwadi, foni dzenhare dzakapinda muupenyu hwezuva nezuva makore makumi maviri nemakumi maviri apfuura. Uye kuwedzera kwekufa kwe "zvikonzero zvisina kufanirwa" hakuiti. Panguva imwecheteyo, hatifaniri kukanganwa pamusoro pemigumisiro isingazivikanwi inogona kuonekwa mumarudzi anotevera. Chiito chechinhu chero chipi zvacho chinokonzerwa nemagetsi emagetsi anowedzera nechokuita. Kana iwe ukafambisa chupu 10 cm kubva munzeve, kuwedzera kwekujekesa kuchaderera nechinhu chezana. Ndicho chikonzero ichi kuti zviri nani kushandisa maoko asingasununguka pakutaura. Uye kuitakura kwete muhomwe yejasi, uye muhomwe. Usagare pedyo neTV: inobudisa miviri-iyi ndiyo mutemo, isu takarangarira kubva pazera remakore. Ichokwadi, hazvizivikanwi izvo vabereki vainyanya kutya: mazairo kana kusada kuonekwa kwezvirongwa zvevanhu vakuru. Asi chokwadi chinoramba: ikozvino isu tinonyatsodzivirira vana vedu kutarisa TV. Masayendisiti akaratidza kuti mhirizhonga yedu haisi yepasina: muviri uri pangozi kubva kare kare kinescope TV uye vataridzi vane ma CRT (cathode ray tube). Pfungwa yeCRT inobva pakubudiswa kwe electrons uye kubhururuka kwavo pahwindo, iro rinofukidzirwa nehuwandu hunoratidzika. Somugumisiro weizvi, chiedza chekuoneka cheavelength chaiyo chinowanikwa (chaizvoizvo, mufananidzo wevaravara unowanikwa pachikona). Zvechokwadi, iyi inonzi X-ray mihizha, asi ine simba rakaderera. Izvo zvikwereti zveRTT zveTV uye vataridzi vese vane zvigadziro zvekudzivirira zvakakosha, izvo zvinodzima zvachose miviri yakaipisisa.
Miridzo kubva kuTV
Mhinduro yakananga ndeyekutsiva CRT TV nekristani yemvura kana plasma. Kuti urege kuve nehutano hwekukuvadza, nyanzvi dzinokurudzira "kuchengetedza kure": kuti ive iri kure zvisingasviki 1.5 m kubva TV. Edza kusagara kumashure kwekushanda kwevatariri ve CRT nemavhevhizheni, usavaisa pedyo nekusimbiswa kwekodhoni masvingo, sezvo izvi zvinotungamirira kune kuonekwa kwe "kuratidzwa" kwemazuva. Nharaunda kubva kumashure kwenyaya yacho kumadziro haisi pasi pe50 cm.
Radiation kubva kuma microveve ovens
Pfungwa ye "microwave oven" haisi chokwadi, nokuti microwave radiation inoshandisa yakareba ye-centimita 12 (ine nguva inokwana 2.45 GHz). Mavhinga anopinda mukati mechibereko kune zvimwe zvakadzika uye anodziya ma molecules emafuta nemvura. Zvadaro moto unopisa hunyoro hunoendesa kupisa huri mukati memvura. Kudzidza kwenguva refu pamusoro pemigumisiro yemirairo kubva kuma microveve ovheni pavanhu havana kusimbisa ngozi yakawanda yekenza. Bhuku rezvigadzirwa zvehupenyu kubva kuTrinth University, San Antonio, Texas rakapedza gore nehafu richidzidza kushanda kwema microwave mazai emhuka. Imwe magwe ane tumarara yekenza yakaiswa mumagariro ekuvhara mavara, apo yaive yakarongerwa irradiation kwemwedzi mina. Mazana zana ekugadzirisa makirani mumakwikwi akafanana emagetsi akaiswa pachena nechiedza. Iyo kuongororwa kwemigumisiro haina kubudisa chero zvakakosha zvakasiyana mukugadzirwa kwemakumbo uye kurarama kwemhuka kwenguva refu. Rega kutya uye kutya, asi unakidzwa nemukana wokukurumidza kushambidza kana kusanidza ndiro. Nekushanda kweuchivhowa, iyo iri kure nemamita masendimita mashanu kubva mairi, mihizha inopera zvishoma pane yefoni ye GSM iri kure. Asi panguva imwe chete tinoshandisa foni kumusoro, uye hatizopfuuriri zvakasimba ku microvheve. Mushure mengozi yeChernobyl makore akawanda apfuura, asi vanhu vanove nekutya mahara. Izvo zvakasikwa, nokuti mamwe radionuclides anogona kuora nokuda kwemazana nemazana emakore, anosvibisa ivhu nemvura. Sezvo uchingoratidzwa nemirairo, zvipenyu, zvechokwadi, zvine ngozi. Kutya kwedu "kwakasvibiswa" nemashoko ekuodza mwoyo eSES kunotambudza pamisika yemaguta makuru: zviuru zve kilogram ye "zvakasvibiswa" zvinowanikwa gore negore.
Radiation radiation
Kana nyukliya inenge yakawanda kana kuti yakawanda inopfuura nehutachiona haisi kukonzera kufadza asi ionization yeatomu, saka sero rinorarama rinoratidzika risina kukwana. Izvi zvinotungamirira pakuumbwa kwenhamba yakawanda yezvitsvaga zvemasununguko, izvo zvinoparadza zviketani zve macromolecules (mapuroteni uye nucleic acids), izvo zvinoita kuti masero masero afa, kubuda kwekenza nekuchinja kwemasero anowanzo. Mikana yekuonana mumuguta rine simba rine mazaisai madiki. Nhau dzokuti mumadziro ezvivako zvitsva zvakawanikwa zvidimbu zvezvinhu zvinoshandiswa ne radioactive, nerufaro, zvakagara mumavambo ekuma90. Uye iye zvino mazhenje emasvingo matsva anoongororwa nemakomisheni anokosha pamberi pekugashira kwehurumende. Asi mhedzisiro yemubhadharo weChernobyl ichiri kunzwika: gore negore rinopfuura 100 kilo yemarubriki e-radioactive uye mushroom inotorwa kubva kutengeswa. Saka, zvakakosha kudya zvokudya, izvo zvinobatsira kubvisa radionuclides kubva mumuviri. Chokutanga pane izvi, izvi ndezvine michina ine selenium, iyo inowanzoshandiswa, uye inodzivirira kuumbwa kwemakumbo. Inowanikwa mugungwa munyu, chiropa chechipfuwo, mazai, hove dzegungwa. Pamusoro pezvigadzirwa zvemichero, selenium yakazara negorosi yegorosi, yakasimwa gorosi zviyo, pamwe chete nezviyo uye garlic. X-ray masimba ane simba anogona kukwanisa kupinda mukati kana kupinda mukati moutano chero hupi zvayo. Fluoroscopic equipment, mammogram kana kombiyuta tomograph - izvi zvishandise zvinoshandawo pa-ray-ray radiation.
