Exactly Natuaral fission reacxtins creatng even more nuclear waste.

Any isotope with a half life of more than a few hundred years isn't very 
naturally  radioactive.

That's the point the greentards™ cant grasp. If its going to be around 
thousands of years, its not very radioactive AT ALL.

Precisely,. The longer it lasts the less dangerous it is,

The Greem Marxists love to conflate 'highly radioactive' 'lasts 
thousands of years' but its  simply a propaganda lie.

That's what I have been saying. Stuff with a half life of a few hundred 
years is the problem, and a pyramid that works for 5000 years is plenty 
good enough
