WebbThe harmful effects of radiation /**/ If radiation collides with molecules in the air or in your body, it throws out of them electrons. By throwing out electrons you produce charged … Webbsuch as the sun. Becquerel had discovered radioactivity. Becquerel used an apparatus similar to that shown in Fig. 3-7 to show that the radiation he discovered could not be x-rays. X-rays are neutral and cannot be bent in a magnetic field. The new radiation was bent by the magnetic field so that the radiation must be charged and different than ...
