The atoms become some other type of atom. In the process, they emit some radiation, which contains energy. The radiation they emit typically include one or more of the following: alpha particles (helium-4 nuclei), beta particles (electrons or positrons), gamma rays, and neutrinos.
The atoms of radioactive elements disintigrate, emitting particles and radiation, and mutating to atoms of other (daughter) elements.
In that case, the radioactive materials will pollute the atmosphere.
The DOT (Department of Transportation) class for radioactive materials is Hazardous. The specific Hazard number will be determined by the exact name of the radioactive materials. Special permits and placarding are needed for vehicles carrying hazardous materials. The DOT class is categorized into 9 classes according to hazardous materials transportation. Class 7 is the general DOT class for radioactive materials.
Radioactive materials decay at predictable rates
Hazard Class 7 is the class for radioactive materials.
"The distinctive symbol used to identify radioactive materials is the
It is an area that is contaminated with radioactive materials.
No, some radioactive materials are not solids. Most radioactive materials are solids (uranium, plutonium, isotopes of many other materials) Some radioactive materials are gases (Radon) or isotopes of gases (Tritium, carbon fourteen, etc.)
Radioactive substances are the things that put off radiation. These could be radioactive waste, or even radioactive materials not yet used.
Detonation of a nuclear device, discharge of radioactive materials (whether accidental or deliberate), spillage or distribution of radioactive materials.

of course
The unwanted presence of materials containing radioactive atoms on other materials.
