Positrons are the same in the sense that they don't penetrate far into the skin, but when they collide with a particle in your body, gamma rays are generated by matter-antimatter annihilation. And gamma rays are very bad for you, indeed, as they have both high energy and can easily pass through your tissues.
As an introduction to our nemesis in this question, positrons are electrons that have positive instead of negative charge. They pull of this feat by being the antimatter version of electrons. Now, beta decay by itself really isn't all that dangerous unless you eat a beta emitter - beta particles/electrons have enough energy to burn the skin but not enough to cause serious damage.
