Indeed, I worked in nuculear {} twice... the first time I quit the first day as
I found the guys were careless.
Then serendipity had it I worked there again, in an other department, years
later.
Some years after I left and started my own business I did read in the paper
that whole place got contaminated..

It all depends.
Later ... we had the Chernobyl fallout, and where I worked the filters in the
aircos were hot (radiation) and had to be properly disposed.
That made me want to measure things, by that time I lost my nuculear fear btw,
But nobody died, vegetables in your garden you were not recommended to eat.
I did see a youtube video about the Chernobyl area where wildlife is
flourishing,
mostly due to the absence of people hunting it I think.
That video was removed...

In the F*ckupshima disaster exactly 1 person died of radiation IIRC.
Hundreds die each year in coal mine accidents..

Ruling the masses by fear is what governments do now, I did lookup some numbers
and here in 2018 more people died than in 2020..
Big farma sells and it sells untested mRNA shit that several very healthy
people have already died from and is not tested over generations,
so will the kids you have be OK? Remember softenon.
It is about big money control and politicians that are puppets of big money and
completely clueless about medicine
but abuse the lockdown to control everything from chat groups to people moving
about.
UNLESS there is a revolt they will keep locking everybody down then give you a
chip implant
so they can remotely kill you if you do not comply with their follies, now they
use the police for that.
OK,

That one uses a small geiger muller tube, basically contains gas between 2 high
voltage electrodes that gets ionized if high energy particles hit it
and then becomes conductive for a moment causing a small current peak.
Several such high energy particles per minute is normal at ground level, on
airplane level with less protection by the atmosphere
much more, in space even more than that
scroll down for the picture of the tube next to the GPS module, or:

For gamma spectrometer I use crystals from ebay in front of the
photo-multiplier tubes like these:
 NaI(Tl) 30x30 Scintillation Crystal Detector
or plastic Scintillation rods
 http://panteltje.com/pub/crystal_relatve_to_world_img_3123.jpg
both give of a light flash when a high energy particle hits, this is then
amplified very many times by the PMT (photo mutiplier) so you
get an other impulse that you can count, and in the case of that setup can
measure the amplitude of,
this amplitude is related to the amount of energy for each particle, and that
depends on what material is 'decaying' releasing the particle
so you can identify what radiates, and see who's bomb it was.... from the
spectral composition.
Enough info?
