Polonium does not have a distinct odor. It is a radioactive element that is odorless. The health risks associated with polonium stem from its radioactivity rather than any smell it may have.
probably mal nutrition
The LD50 for polonium-210 is under 1 microgram; it is a very high radiotoxicity.
Polonium is extremely radioactive and dangerous; plutonium is sometimes used for the treatment of bone cancers.
According to the work of the Curies, which action would increase the radioactivity of polonium? Dissolve the polonium in a solvent.Heat the polonium until it becomes a gas.Expose the polonium sample to light.Increase the amount of polonium.
like cancer,asthma(problems in breathing) etc.
Scurvy and rickets are some health problems caused by lack of nutrition, but I don't know many more.
