1. Some of the beta radiation is absorbed while passing through the product. 2. Beta radiation causes the most damage if its particles are ingested or inhaled.3. The companies are using different substances to produce the beta radiation . 4. Liquid scintillation counters are an efficient and practical means of quantifying beta radiation 5. He elected to study beta radiation under Hans Geiger in Berlin. 6. Other experiments showed beta radiation , resulting from decay and cathode rays, were high-speed electrons. 7. In all of these therapeutic uses, 131 I destroys tissue by short-range beta radiation . 8. Tritium, and Strontium-90, which seeks the bones in the human body, emit beta radiation . 9. This usually has a sliding shield which enables discrimination between gamma and beta radiation . 10. Furthermore, 123 I emits gamma radiation, while 131 I emits gamma and beta radiation .
