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 follows
241Pu has a half life of 14 years
232U has a half life of 68.9 years
So 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).

∙ 11y agoThe specific activity is different for each isotope and U and Pu have many isotopes.
But:
- the most common isotope of uranium (238U) has a specific activity of 3,3.10-7 Ci/g
- the most common isotope of plutonium (239Pu) has a specific activity of
6,2.10-2 Ci/g
Compared, plutonium is more radioactive.

∙ 13y agoPlutonium releases more energy in a nuclear reaction then uranium.
Wiki User
∙ 12y agoPlutonium is more dangerous: more toxic and radioactive.
Wiki User
∙ 12y agoIf you think to critical mass, plutonium has a critical mass smaller than the critical mass of uranium.
Also plutonium is more toxic and dangerous.

A radioactive element often used in nuclear power stations?
Uranium 235 or Plutonium 239
Is plutonium the result of of the alpha decay of uranium?
Plutonium is not related to uranium isotopes radioactive decay; plutonium is obtained by nuclear reactions from uranium isotopes only in nuclear reactors.
Which radioactive element is used in nuclear reactors?
Usually Uranium 235 but sometimes Plutonium 239
Is plutonium more powerful than uranium?
No, plutonium is a different element entirely.
Which all radioactive elements are used for nuclear reactors in India?
well its usually uranium 235 or plutonium they are both effective
Which material type is more dangerous plutonium 239 or uranium 235?
Plutonium is more toxic and radioactive.
Does plutonium have isotopes that are all radioactive?
All the uranium isotopes are radioactive.
Which element is more radioactive than uranium?
polonium, radium, plutonium and many others
What is a naturally occurring element that is radioactive?
Uranium and Plutonium
What is more radioactive than pure uranium?
Many radioactive isotopes are more radioactive than the naturally occurring uranium isotopes:All fission product isotopes are more radioactive (e.g. iodine-131, strontium-90)Most radioactive isotopes in the uranium --> lead decay chain are more radioactive (e.g. radium, radon, polonium)Plutonium is more radioactiveTritium is more radioactiveCarbon-14 is more radioactiveArtificially produced uranium isotopes are more radioactive (e.g. uranium-233, uranium-236)etc.
Are uranium plutonium and hydrogen dangerous?
1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and a radioactive chemical element. 3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated. Plutonium: the same characteristics, but it is more toxic and radioactive. Hydrogen: it is a cause of severe explosions.
Which element is most radioactive plutonium uranium or cerium?
All the isotopes of uranium and plutonium are radioactive; plutonium isotopes have a greater specific activity. For cerium: the isotopes 136Ce and 142Ce are possible to be radioactive but having very long half lives and a not significative radioactivity.
What 2 radioactive elements were chosen for the atomic bomb?
Uranium and Plutonium
A radioactive element often used in nuclear power stations?
Uranium 235 or Plutonium 239
Can anyone give you an example of a radioactive substance?
H3, Deuterium is radioactive. Uranium and plutonium are radioactive and are used in atomic bombs.
Is plutonium the result of of the alpha decay of uranium?
Plutonium is not related to uranium isotopes radioactive decay; plutonium is obtained by nuclear reactions from uranium isotopes only in nuclear reactors.
What is plutonium abundance earth's crust?
Only a trace of plutonium is naturally found in the earth's crust. And it is always found with uranium because it is made by uranium's spontaneous fission, neutron release, and the subsequent neutron capture by another uranium nucleus to form the plutonium atom. Plutonium is not formed by the death of a star in a super nova like uranium is. Uranium is the heaviest element formed in that event. That's why there isn't any plutonium around as an ore. Just the trace amounts found with uranium. We're lucky there isn't a lot of plutonium around. It is highly toxic owing to its hightly radioactive nature. A link is provided to the Wikipedia article on plutonium.
