That the substance is dangerous & explosive.
its nuclei can split apart
A typo. You might, however, be interested to know about Radon, a radioactive noble gas with an atomic number of 86, which is formed from the decay of underground Uranium and can pose a health hazard as it accumulates in poorly-ventilated homes.
physical hazard
hazards means somthing that has dangerouse effect on life of living beings
The atoms structure is unstable and it emits alpha or beta particles that changes the Atom
Do you, perhaps, mean "radioactive"? Yes, radioactive materials can be hazardous. If you literally mean "radiant", i.e. glowing, that's not technically in itself a hazard.
Radon is a colorless radioactive gas considered to be a health hazard.
Hazard Class 7 is the class for radioactive materials.
Radon is radioactive and is actually a fairly common hazard because of this.
Uranium hexafluoride is classified as a radioactive material and falls into Class 7 (Radioactive) hazard class. It is considered a hazardous material due to its radioactivity and potential health risks.
The radioactive placard on a vehicle indicates that the vehicle carries some amount or regulated radioactive material.
You can usually find hazard symbols near dangerous materials or areas like maybe you would find lots of radioactive hazard symblols in chernobyl, where the atomic explosion happened.
Hazard Class 7 is for radioactive materials.
Many hazard warnings exist: flammable, corrosive, toxic, radioactive, explosive, etc.
1. Any hazard, but noble gases are not respirable. 2. Radon is very radioactive and dangerous.
Radiochemical hazard refers to the potential health risks associated with exposure to radioactive materials. These hazards can result from sources such as nuclear reactors, radioactive waste, or nuclear accidents. Exposure to radiochemicals can pose significant health risks, including increased risk of cancer and genetic mutations.
Californium is a very rare and expensive man made metal. But because it is a strong radioactive element californium can be an environmental hazard in the case of an accident.
