Laser radiation is not the same as nuclear radioactivity, laser emissions take the form of intense, coherent focussed light, in varying spectrums, from x-ray lasers to infrared beams.
I once made a reasonably powerful I.R laser emitter myself, lasers do not typically emit nuclear radiation, x-ray lasers being perhaps an exception, but you aren't going to find one of those in your £2.99 laser pointer.
Nuclear radiation is the product of decay of unstable elements such as the actinide series, and promethium, to give rise to various forms of particles and gamma radiation, which are byproducts of the particles dissintegration.
A powerful laser will nevertheless burn out the retina of your eye, or in the case of very powerful ones, cut through steel, but damage thusly done, is because the laser emits a beam of intensely focussed, coherent energy, which will cause burns.
