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
Radon gas is a naturally occurring radioactive gas and is not typically bought or sold by the gram. Therefore, it does not have a set cost per gram like other substances. Radon gas is a health hazard and is typically measured in picocuries per liter (pCi/L) in indoor air. Testing for radon levels and mitigating high levels in homes is important for public health and safety.

Radium (Ra)
Uranium and radium, and a number of others, are natural elements found in the ground, and they are radioactive.
Radium (Ra)
The radioactive element that begins with the letter R is radium. Radium is a highly radioactive element and is found in uranium ores. It emits alpha, beta, and gamma radiation.
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.
Radium naturally decays into radon, which is a radioactive noble gas. This decay process is one of the steps in the radioactive decay chain of uranium-238.
Radioactive yes, synthetic no. Radium is found in nature in very small trace amounts usually in uranium ore deposits.
Radium has not its own minerals; radium exist in extremely low concentrations in uranium and thorium ores.
Uranium is the first element known to be radioactive. It was discovered by Henri Becquerel in 1896.
