Yes, but from many years radium is not used for watches (or other measuring instruments) dials.
No, radium is very radioactive (emitting alpha, beta, AND gamma) and acts chemically as if it was calcium. This causes any radium that enters the body to become incorporated into the bones, where its intense radiation kills the cells that make bone (causing the bones to weaken and eventually crumble) and the blood producing cells in the marrow (causing anemia and weakening the immune system allowing severe infections to develop).
Radium and polonium are both radioactive elements that can emit harmful radiation. Radium was used in the past for its luminescent properties, while polonium is known for its use in static eliminators and sources of heat in space missions. Both elements have toxic effects on the human body if ingested or inhaled.
Radium is a highly radioactive material that can emit harmful radiation, posing health risks when worn close to the body. If you have a silver necklace that contains radium, it is important to handle it with caution and consider getting it properly disposed of by a professional.
Absolutely not. Radium is a highly radioactive alkali earth metal, and, though some of the elements from this chemical group are critical for life (if you don't have them you die), this one is to be avoided if it is at all possible. Zero radium is a good amount to have in your body any time. All the time, too.
well they are not exactly not really harmful they sometimes are harmful because they are scared....

Fortunately radium don't exist normally in the human body; after an unhappy internal contamination radium can be fixed in bones.

Is limestone in well water harmful to the human body
uilo
the harmful bacteria live in air,human body etc.
nön pathogenic fungi is a grp of fungi which are not harmful to the human body or it is commensal to human body.
No, Cobalamin (B12) is a vitamin necessary to the human body.
