yes there are.
" Unintended consequences? " Scientific theories are explanations of natural phenomenon. Only humans can make " consequences ", theories explain things.
Any link between radium and...poems !
1. Radium has 45 isotopes and nuclear isomers. 2. Radium has no known today allotropes.
Both radium and polonium are radioactive elements and are not stable.
Polonium and radium are continuously studied, but not so much.
Any link between Dalton and polonium&radium.
As radium is radioactive, radium chloride would also be radioactive. Any compounds make with any radioactive material are radioactive, and they cannot be "not" radioactive. Radioactive material doesn't really care if it is "alone" or in compound; it will be radioactive in any case.
Radium is not used as a component of luminescent paints from about 80 years !
Of course, many scientists worked with radium and polonium.
Any link exist between X-rays and polonium&radium.
1. Radium has 88 protons. 2. Radium has not... americium !
No, any link
