Imma assume its how ionising it is?
also, you can comment on the type of radiation too :P

Differences between radiation from uranium and that from a lamp?
Uranium's radiation is far more ionising due to high concentration of alpha emission (low levels of beta and gamma). Lamp radiates mostly infrared (low level of visible light, minimal UV); a low freq EM wave that's barely ionising, far safer exposure.

Unlike the lamp, uranium's radiation can't be seen, is difficult to detect. Lamp's radiation travels faster (c = 3 x 10^8 ms^-1), uranium's mostly at particle speeds << c, thus more easily absorbed. Both factors increase danger of uranium exposure.
