There already exists such a technique with a certain isotope of boron
attached to substances which are preferentially bound or taken up by
tumor cells. The boron disintegrates when irriadiated with certain
low-energy radiation, killing the cell it is attached to (or something
like that).
Can't give you any lit refs, but I'm sure you can find something on
medline.
