Imirasire ni iki?

Imirasire, muburyo bwumuraba cyangwa ibice, ni ubwoko bwingufu ziva ahantu hamwe zijya ahandi. Guhura n'imirasire ni ibintu bisanzwe mubuzima bwacu bwa buri munsi, hamwe n'amasoko nk'izuba, amashyiga ya microwave, na radiyo y'imodoka biri mubizwi cyane. Mugihe ubwinshi bwimirasire idahungabanya ubuzima bwacu, ubwoko bumwe burabikora. Mubisanzwe, ibipimo byo hasi byimirasire bitwara ibyago bike, ariko dosiye ndende irashobora guhuzwa ningaruka ziyongera. Ukurikije ubwoko bwimirasire yihariye, ingamba zitandukanye zirakenewe kugirango twirinde ubwacu nibidukikije ingaruka zabyo, byose mugihe dukoresha uburyo bwinshi bukoreshwa.

Imirasire ni iki?

Ubuzima: Uburyo bwo kuvura nkubuvuzi butandukanye bwa kanseri nuburyo bwo gufata amashusho bwerekana ko ari ingirakamaro kubera gukoresha imirasire.

Ingufu: Imirasire ikora nk'uburyo bwo kubyara amashanyarazi, harimo no gukoresha ingufu z'izuba na kirimbuzi.

Ibidukikije n’imihindagurikire y’ikirere: Imirasire ifite ubushobozi bwo gukoreshwa mu kweza amazi y’amazi no guteza imbere amoko y’ibimera ashobora guhangana n’ingaruka z’imihindagurikire y’ikirere.

Inganda na siyanse: Mugukoresha tekinoroji ya kirimbuzi ishingiye ku mirasire, abahanga bafite ubushobozi bwo gusesengura ibihangano byamateka cyangwa gukora ibikoresho bifite imitungo yiyongereye, nkibikoreshwa mu nganda z’imodoka.

Ubwoko bw'imirase
Imirasire idafite ionizing
Imirasire idahwitse bivuga imirasire ifite ingufu nkeya zidafite imbaraga zihagije zo kwambura electron muri atome cyangwa molekile, zaba ziri mubintu bidafite ubuzima cyangwa ibinyabuzima. Nubwo bimeze bityo ariko, imbaraga zayo zirashobora gutuma molekile zinyeganyega, zikabyara ubushyuhe. Ibi bigaragazwa nihame ryimikorere ya ziko ya microwave.

Umubare munini wabantu ntibashobora guhura nibibazo byubuzima bituruka kumirasire idafite ionizing. Nubwo bimeze bityo ariko, abantu bakunze guhura ninkomoko yimirasire idafite ionisiyoneri barashobora gusaba ingamba zihariye kugirango birinde ingaruka zishobora kubaho nko kubyara ubushyuhe.

Imirasire ya Ionizing
Imirasire ya Ionizing ni ubwoko bwimirasire yingufu zingirakamaro kuburyo ishobora gutandukanya electron na atome cyangwa molekile, zitera impinduka kurwego rwa atome mugihe zikorana nibintu birimo ibinyabuzima. Ihinduka nkiryo risanzwe ririmo kubyara ion (atome cyangwa molekile zikoresha amashanyarazi) - niyo mpamvu ijambo "ionizing" imirasire.
Ku rwego rwo hejuru, imirasire ya ionizing ifite ubushobozi bwo kwangiza ingirabuzimafatizo cyangwa ingingo ziri mu mubiri w'umuntu, kandi mubihe bikomeye, bishobora gutera impfu. Nyamara, iyo ikoreshejwe neza kandi hamwe nuburinzi bukwiye, ubu buryo bwimirasire butanga ibyiza byinshi, harimo gukoreshwa muburyo bwo kubyara ingufu, inzira zinganda, ubushakashatsi bwa siyanse, no gusuzuma no kuvura indwara zitandukanye, harimo na kanseri.
