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".
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.
Radium. Atomic number 88
You can't buy it.The most stable isotope of radon has a half-life of about 4 days (contrast this with the first element most people think of when they hear the word "radioactive," uranium, where the kind used in nuclear reactors and atomic bombs has a half-life of seven hundred million years, and the most common isotope has a half-life of about five billion years).Most people who need radon ... and there are very few ... generate it in situ from a solution containing radium that costs about $6,000 per milliliter, with each milliliter containing about 15 picograms of radon at any given time. A gram of radium produces about 1 mm3 of radon gas per day, so to get a gram of radon per day, you'd need about 101 kg of radium. Radium is not commercially available in those quantities, so the ultimate answer is that it's literally priceless; you cannot buy a gram of radon at any price.

Radium (Ra)
Uranium and radium, and a number of others, are natural elements found in the ground, and they are radioactive.
Radium (Ra)
She discovered the elements Polonium, which was named after her homeland, and radium. Polonium is 4x more radioactive than uranium and radium is 10x more radioactive than uranium.
No. The Curies did not discover uranium. They discovered polonium and radium, of which polonium is more radioactive.
Radioactive yes, synthetic no. Radium is found in nature in very small trace amounts usually in uranium ore deposits.
All these elements are natural, solid and radioactive.
polonium, radium, plutonium and many others
the main element extracted was radium
Disadvantages of uranium: 1. Uranium is a possible contaminant 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.
