21. I would particularly like a list of sources of just beta radiation , and with a long halflife. 22. In addition, beta radiation was detected in areas beyond the levees designed to hold back contaminated water. 23. Some types contain a source of beta radiation to start ionization of the gas that fills the tube. 24. As a result, there is a higher chance that the beta radiation from tritium will trigger tumor growth. 25. He elected to go to the Physikalisch-Technische Reichsanstalt in Berlin in 1913, to study beta radiation under Hans Geiger. 26. Following embolization of the yttrium-90 glass microspheres in tumorous liver tissue, the beta radiation emitted provides a therapeutic effect. 27. :Well, the amount of beta radiation you detect would reduce as some function of the distance from the source. 28. Samarium-151, produced at lower yields, is the third most abundant medium-lived fission product but emits only weak beta radiation . 29. They produce beta radiation , which causes high ionization inside the lamp without being able to escape from the lamp. 30. The eye lens seems to be the most sensitive organ to beta radiation , even in doses far below maximum permissible dose.
