Why is a sample of radioactive material always a little warmer than its surroundings?

Radioactive material is warmer than the surrounding material because radioactive material is constantly breaking down. When material breaks down, that means that energy is constantly getting released. When energy is released, it produces warmth.

∙ 15y agoThey are warm because they are breaking down by radiating off particles with carry energy from the atom to surrounding environment and exciting that environment (causing movement.) Anything giving energy to the environment creates warmth.
Wiki User
∙ 15y agoBecause the radiating alpha or beta particles give internal energy to the atoms of the sample.

∙ 14y agoBecause radium being strongly radioactive emit by radioactive disintegration radiations: alpha, beta, gamma and release energy as heat.

Why is nuclear energy bad for the world?
Nuclear energy produces long-lived radioactive waste. There is also a possibility of accidents that would release radioactive material into the environment. However, there is little to no greenhouse gas or smog produced by a fission plant, so (like everything else) it's a trade-off. Nuclear plants also release far less radiation when operating properly than a coal power plant does. This is because coal contains radioactive uranium and its various products xx
How long does it takes a radioactive material to decay?
Nuclear explosions produce both immediate and delayed destructive effects. Immediate effects (blast, thermal radiation, prompt ionizing radiation) are produced and cause significant destruction within seconds or minutes of a nuclear detonation. The delayed effects (radioactive fallout and other possible environmental effects) inflict damage over an extended period ranging from hours to centuries, and can cause adverse effects in locations very distant from the site of the detonation.

What would happen if promethium did not exist?
Not much. We could make some in the physics lab. But there is only the barest trace of this radioactive material anywhere on earth. Promethium has no stable isotopes, and the longest-lived isotope has a half-life of only about 17.7 years. This stuff disappears almost as rapidly as it is created in nature, and only a couple of elements produce it by radioactive decay. If there was none around, we wouldn't miss it much since there is so little to begin with. Use the link below for more information.

Is marble radioactive?
If you are talking about the geological stone called marble then no it is not. If you are referring to the little stone or glass balls used in games then some of them are a little radioactive. If you have glass marbles you can check this by shining a black light on them. If they glow they have a little radioactivity in them. Not that it is enough to harm anyone. Anything that glows in the dark is radioactive.
If you start with 20mg of a radioactive substance after 1 half life how much daughter material would you have?
It depends upon the particular atom in the question. The amount of daughter material will be little less than 10 mg. It will not be 10 mg as you may expect. Some of the mass is lost as energy. This amount is too little. Yet the energy released is too much. The mass is converted into energy as per the equation of Einstein. That is E = m c 2. Here the c, means speed of light is 3,00000000 m/s. Square of c is 9 0000000000000000 . It is pretty large than you can imagine. The amount of the radioactive material will be exactly 10 mg. That is how the half life of the radioactive material is defined. As on today, there is no method to convert the entire mass into energy.
Organism's surroundings called?
the space an organism occupies is called a niche the surroundings of and organism would be its habitat I hope this is what you meant by organisms surroundings? if not restate question a little more clearly
How much does it cost to remove cobalt?
The removal of cobalt can cost from a little to a lot, depending on what it is to be removed from and in what form it is present. A small block of it sitting on a table can be picked up and carried away. Powdered cobalt scattered in a deep-pile rug can present other problems. And this is non-radioactive cobalt. If the cobalt that needs to be removed is radioactive, there are a ton of complicated proceedures to do that. Sometimes things contaminated with radioactive material cannot be recovered and must be disposed of whole in a radioactive waste disposal site. Links are provided.
How does polonium effects us today?
Very little. It is a rare radioactive element
