Radioactive elements are dangerous because cells within the body preferentially incorporate radioactive atoms in their structures.

B

Since radioactive elements have unstable nuclei, they all form cations due to the loss of electrons.

C

Only those radioactive elements are dangerous which are artificial, naturally radioactive ones are safe.
