But you increase its half life by 40 years (explain in comments)

So Oganesson is a Synthetic EXTREMELY Radioactive (118 Atomic level) Material but its half life is like a few mililseconds.

i mean, if you increase the halflife to 40 years dont only expect a living freind but also a nobel prize.

how would they be alive wouldn't the radiation kill them?

i did a little bit of research and the first thing you should know is how much you have. because having a lot of anything will almost always kill you.
because i couldent find the ratio of absorbed particals to non absorbed particals i just went with 100% radioactuve absorbtion. bismuth 207 has a roughtly similar half life here with 32 years. one decay of bi 207 has 3.363E-13 jouls in it. a dangerous amount of energy absorbed is 1 joul per kilogram of mass you are. so you would need 2.9733E12 atoms of Bi 207 to decay at once to generate a harmful amount of radiation. this is far less than one mol of bi 207. but in order for that many to decay in a harmful intervle we would need several times the amount here. still kinda low though. would not recomend putting radioactive material like this near anyone that is un protected.

I don't literally mean in a waste can, I mean the raw material, and a lot of it. (although i did not mention it in the image so good point there) but it could be an undiscovered isotope of 118 although its not implied in the image and therefore your statement is correct as of my knowledge.

if the barrel was a big as your torso you would be royaly screwed. uranium 235 has like a half life of millions of years. im not sure how safe that is. also last i checked adding more or removing neutrons only makes the atom less stable, it would be unlikly to find a stable isotope.

until we find a more stable isotope of Oganesson i guess we are stuck with the 294Og isotope for now, but its probable that the leftover livermorium wold kill you

i mean, we cant even make a whole lot oganesson. fabricated in a lab and all.

yes due to its 0.89sec half life and it is extremely hard to create so we are better off just sticking with tenessine as for now.

tenessine for what?

as are most atomic element with more than 1 discovered isotope
