I'm guessing kryptonite.
No, Kryptonite is a fictional mineral from the Supermanseries.
Blue kryptonite - it improves Superman's health and frees him from red kryptonite's unpredictable side effects. Blue kryptonite only affects Bizarro - he feels weak.
Kryponite can kill superman, Magic can too. But doomsday actually killed him but he came back. I hate superman though.
green Cristal
All of the following affect all Earth 1 (main continuity) Kryptonians, including Superman. Green kryptonite affects Superboy (Kon-el, who is only half Kryptonian), but I am not sure about the other colors where he is concerned. Green Kryptonite causes debilitating pain and illness, significant loss of powers, and eventually death. Red Kryptonite causes all kinds of strange, random effects, from aggression to apathy, power loss, and unexpected shape-shifting Gold Kryptonite causes loss of powers by removing the Kryptonian's ability to process yellow sunlight. Originally this was a perminant effect, but in more recent continuity the duration of power loss is given at 15 seconds. Blue Kryptonite is the Bizarro version of Green Kryptonite. It affects Bizarro the same way Green K affects Superman. It has benificial effects on Earth 1 Kryptonians. Black Kryptonite has the ability to split a Kryptonian into two beings, one good and one evil. White Kryptonite destroys plant life within a certain radius, whether the plants are Kryptonian or not. Pink Kryptonite apparently causes Superman to hit on Jimmy Olsen. It was only used once, in the second Supergirl series, and was probably intended as a joke.
Plutonium is more toxic and radioactive.
It is relative easy to obtain uranium; the preparation of plutonium is more difficult and extremely dangerous.
Plutonium is more dangerous: the specific activity is greater, the critical mass is smaller, the chemical toxicity is greater.
No, plutonium is a different element entirely.
Contamination with plutonium is very dangerous because plutonium is very radioactive and toxic.
Plutonium is extremely toxic and radioactive, being very dangerous.
plutonium
Plutonium is toxic and radioactive; a contaminated area is dangerous for humans.
Being very toxic and radioactive plutonium is extremely dangerous.
There are numerous isotopes of both plutonium and uranium ( all radioactive) thus it is not easy to say which element is more radioactive. However the half lives of the most active isotpe of each compound is follows241Pu has a half life of 14 years232U has a half life of 68.9 yearsSo in terms of activity, Plutonium is more radioactive; however uranium stays radioactive for a longer time.The specific activity of plutonium is greater than the specific activity of uranium (comparison between 239Pu and 238U).
The critical mass of plutonium is lower, plutonium is not so expensive as highly enriched uranium, the technology to obtain plutonium is more simple than the isotopic separa-tion of uranium, etc.
Because plutonium is toxic and radioactive the contamination of the environment is very dangerous.
