Can radium bombs be very destructive as it is million times radioactive than uranium?
The reason why an atomic bomb produces such a large explosion is that certain radioactive isotopes, such as U-235 or plutonium, can be made to undergo a chain reaction in which all the atoms will decay in a very short period of time (a small fraction of a second) releasing all the energy at once. Radium does not do that. However, if you had a substantial quantity of radium you could certainly use it to create radioactive contamination which could induce cancer in many people. That is known as a "dirty bomb".
The difference between nuclear waste and nuclear weapons?
The exact contents of radioactive waste from a nuclear power plant and radioactive fallout from a nuclear weapon can vary widely but are likely to be similar in their primary isotopes.The major difference between the radioactive waste from a nuclear power plant and radioactive fallout from a nuclear weapon is that the waste is normally contained and will not enter the environment (unless an accident happens) while the fallout is dispersed into the environment and is carried by the wind (sometimes all the way around the world multiple times).
How did the chorus originate?
People go through times and want to express there feelings and do it through music.
What can music do?
Music can inspire you and help you through ruff times.

He will stand by you through bad times and good times
How much energy is released if a sample 0.025 kg mass through radioactive decay?
2.25 times 10 to the 15
What does the word decay factor mean?
Some quantities decrease by a fixed proportion (not fixed amount) in each time period. Typical examples used in school mathematics are depreciation or radioactive decay. The value of an asset (often a car) is assumed to lose x% of its value every year. That is, at the end of each year, its value is (1-x/100) times what it was a year earlier. Similarly, radioactive substances lose y% of their mass through nuclear decay in each time period. The factor (1-x/100) is known as the decay factor.
Does Mars have lava?
Mars does not have lava, but probably has magma due to radioactive decay.
Does radioactive decay give evidence that the earth has changed?
Information on radioactive decay is used for radiometric dating. It can be used to determine the ages of rocks, fossils, and younger organic materials. Clearly, the earth has changed, and the dating of materials on the earth show this. In the really old times, the surface of the earth had no plants. Over time, the plants developed on the earth, and then came animals. Dominant forms came and went, and all this is in the record, dated to some extent by techniques that use radioactive decay rates. Even the rocks, untouched by life, have changed, and this also can be dated based on decay rates.
Is the percentage of radioactive atoms that decay during one half-life always the same?
No time required for completion of first half life is not same as 2nd one.Even it has been found that time required for 99.9% completion is almost 10 times of half life period.
What is the longest radioactive halflife?
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).
Is molybdenum radioactive?
Molybdenum has both stable and unstable isotopes. One of the naturally occurring isotopes, 100Mo, is very slightly radioactive and undergoes double beta decay with an extremely long half-life (around 7 800 000 000 000 000 000 years, which is about half a billion times the current age of the universe). This means that at natural abundance about 37 decay events per gram of molybdenum per year are expected.
Are daughter isotopes stable?
No. Often a decay product is itself unstable and will decay into something else until a stable isotope is reached. This is called a decay chain. For example, Uranium-238 will decay 15 times through various isotopes until it becomes lead-206 which is stable

What is atomic life?
Strictly it is the half life of a particular isotope of the element. The half life of a radioactive isotope is the time taken for the number of radioactive atoms in the sample to decay to one half. Half lives vary hugely, from times like 10-21 seconds, to the very long, approaching the age of our solar system at 4.5x1012 years.
Are radioactive elements made in a laboratory?
What an interesting question. The answer is however complex.It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".It is in supernova explosions that the radioactive elements are made.
Do cadmium conduct electricity?
Yes. Cadmium is radioactive, with over 50% made up of radioactive isotopes, though the half lives so very long that they can be treated as stable for most purposes.Naturally occurring cadmium is composed of 8 isotopes. For two of them, natural radioactivity was observed, and three others are predicted to be radioactive but their decay is not observed, due to extremely long half-life times. The two natural radioactive isotopes are 113Cd (beta decay, half-life is 7.7 × 1015 years) and 116Cd (two-neutrino double beta decay, half-life is 2.9 × 1019 years). The other three are 106Cd, 108Cd (double electron capture), and 114Cd (double beta decay); only lower limits on their half-life times have been set. At least three isotopes - 110Cd, 111Cd, and 112Cd - are stable. Among the isotopes absent in natural cadmium, the most long-lived are 109Cd with a half-life of 462.6 days, and 115Cd with a half-life of 53.46 hours. All of the remaining radioactive isotopes have half-lives that are less than 2.5 hours, and the majority of these have half-lives that are less than 5 minutes. This element also has 8 known meta states, with the most stable being 113mCd (t½ 14.1 years), 115mCd (t½ 44.6 days), and 117mCd (t½ 3.36 hours).No, Cadmium is not radioactive, though it is toxic.There are, however, several radioactive isotopes of cadmium.
