elements from nuclear power plants:
Here is a short list of
'some' of the
radioactive
elements being released into our environment.
Common radionuclide | radioactive
elements
half - life:
Beryllium.........................2,700,000 years
Calcium..............................100,000 years
Cesium-137...................half life - 30 years
Cesium-135......................2,000,000 years
Rubidium.................47,000,000,000 years
Palladium.........................7,000,000 years
iodine-129......................17,200,000 years
plutonium-239........half life -
24,390 years
strontium-89..............................................53 days
strontium-90................................28 years
tin-126................................100,000 years
uranium-235...........................713,000,000 years
uranium-238...............4,510,000,000 years
The above common radionuclide are being released into our air, water, and
ground 24 / 7......

[For any radioactive substance, the
time required for
one-half of it to disintegrate is called the half-life.
Some of the radioactive byproducts of nuclear
uranium fission have very short half-lives, others, very long.
This concept of "half-life" seems difficult. It is not.
It's mostly just a convenient way to measure the potential
for harm and how long it may last.
If a radioactive substance has a half-life of one day,
we mean that, in the course of one day, half of that
substance will decay or disappear.
In the next day, one half of what is left will
disappear,
in the next day one-half of that will disappear, and so on.
So a substance with a half-life of one day will be reduced
in radioactivity 1000 times in 10 days. Hardly enough left
to do much damage, you might say, within the very short
time of 10 days.
But if a substance has a half-life of
about 30 years
(like cesium-137) it's radioactivity is reduced 1000
times only after 300 years!]
