Will these two places ever be habitable for human life again so they can live without being worried of getting ill of radiation?
A quote from Russian wikipedia:
>С точки зрения воздействия на население в первые недели после аварии наибольшую опасность представлял радиоактивный иод, имеющий сравнительно малый период полураспада (восемь дней) и теллур. В настоящее время (и в ближайшие десятилетия) наибольшую опасность представляют изотопы стронция и цезия с периодом полураспада около 30 лет. Наибольшие концентрации цезия-137 обнаружены в поверхностном слое почвы, откуда он попадает в растения и грибы. Загрязнению также подвергаются насекомые и животные, которые ими питаются. Радиоактивные изотопы плутония и америция сохранятся в почве в течение сотен, а возможно и тысяч лет, однако их количество невелико ([3], с. 22).
It says that the most dangerous fallout contained radioactive Iodine, but it dissipated rather fast (it's half-life is only about 8 days). Right now the most dangerous components are Strontium and Caesium (half-time 30 years). Radioactive Plutonium and Americium can endure for hundreds and maybe thousands years, but there quantity is small.
So predicting the exact time when the radiation level is going to be acceptable for safe living there is rather hard.
Chenbyl locate 12 km away from the NPP, it's almost half of radius the еxclusion zone. Of course, there isn't so much background radiation like it was in 1986, but it's too much for permamnt living, moreover if living so weak people like now.
By the way, even now, almost 20 years later people find places, where dosimeter rolls over.
Thousands of people still live in these areas, and they do not live in safe houses! They go about their daily life as usual. Many are older so still look after their farms and are self-sufficient, and many other people have stayed because it is their home and there is nowhere else to go. There are also around 3000 people still working in the Chernobyl power plant, undertaking decommissioning work which will take years to complete.
Chernobyl will be at least but not for hundreds maybe even thousands of years
The FIRST half life of radiation there is 25,000 YEARS. So consider this when you go house hunting.
no because it is still leaking radiation (the plant), plus the time of some nuke elements to get destroy are thousand of years, so no they won't be
Not during our lifetimes. Someday, yes.
