Again, the question is incorrect. And infrared radiation (high temperature) can? And from what distance? What is the temperature?

Yes, maybe, only if, if ...

The smoke from the explosion of the chaes in which 13 thousand rengets were thrown out per hour and in addition the release of uranium, plutonium, iodine, graphite, neptunium-239, lead, cesium, and more, and at this moment, too, the radiation at elephant legs reaches from 3000-3500 thousand X-rays per hour literally 10 minutes and Tobi Khan

The irradiation rate is 20 μR / h, with such doses you will have terrible consequences from radiation sickness and you will die soon

And in addition, the decay period of each substance, which I have listed is from 10 to 24000 (approximately) years, and this is still a small list of what was released into the atmosphere

According to Wikipedia, there is even such a concept of 'death under the ray'. It occurs at a dose over 120 Gray. I think, to guarantee the effect, a dose of 200 Gray is enough for a person to die, if not instantly, then at least in a couple of minutes.

I don’t know if there will be death from the burn associated with powerful training, or (I want to believe it) the person will die without any visual symptoms.

Although it is possible that competent radiologists will spread my answer to smithereens. I would like to know the opinion of professionals.

I think alpha radiation with an activity of about 100MKi (mega Curie) will fry any living creature to a crisp in a few tens of seconds. You can die from 5 MKi and from 10.

Maybe if the dose is large enough. As far as I know, this did not happen in Earth conditions. Workers who received the maximum exposure in Chernobyl died on average within a month. I think if you suddenly appeared in the vicinity of a neutron star, you would die instantly.

Yes, yes. After all, radiation is made up of two components - directly radiation (which is gamma) and particles (which are alpha and beta).

So, from radiation there is a chance to instantly die well-done. Unlikely from ionized particles. The body will last up to several days.

The picture shows the Chernobyl nuclear power plant. There was relatively little radiation.
