50 years, maybe entire lifespan? There's no guaranty you'll die from effects of radiation in this low environment. However, even a single high energy ray can cause cancer. (like, one click)

The radiation measured with the device in the picture is not the reason why they built the sarcophagus. It's the particles.

GMC-300E+ V4.20 with sbt-11a alpha tube

My statements are "stuff-a-hobbyist-says" and not in any way professional.

A dose of 1.761 mR/h (milli Röntgen per hour) is equal to 17.61 µSv/h (mikro Sievert per hour) or, in the case of an GMC-300 and its calibration, equal to CPM=2700.

This is roughly on a par with my gas mantle test (#21 in http://www.gqelectronicsllc.com/forum/topic.asp?TOPIC_ID=4540 ).

If you were camping on this spot for a whole year, you'd receive 17.61µSv/h * 8760h = 154 mSv.

The occupational (workers in nuclear power stations, medical x-ray facilities, chemists, pilots, ...) whole body exposure limit in Germany is 20mSv per year, in the USA it is 50mSv, so for Germany you got 8 times the yearly limit, in the US only 3 times. However, depending on circumstances the German limit could be increased also to 50mSv.

In addition there is a life-long limit in Germany (not sure about the US) of 400mSv. According to German rules your uninterrupted camping vacation at Chernobyl must not last longer than 2 years and 7 months. h**ps://www.bfs.de/DE/themen/ion/strahlenschutz/beruf/grenzwerte/grenzwerte.html

Mind you: these numbers are set with the intention to keep you healthy for a long life! It does not rule out that you could perhaps camp there for 50 years and still enjoy a healthy life.

Lethal? No, not by a long shot
