| 21. | Beta particles are electrons or positrons and can travel farther than alpha particles in air.
|
| 22. | In some of these cases of disintegration, beta particles ( electrons ) may be released.
|
| 23. | A second blackout effect is caused by the emission of beta particles from the fission products.
|
| 24. | I know how CRT monitors work and I also think I know what beta particles are.
|
| 25. | Beta particles are high energy electrons or positrons.
|
| 26. | To monitor beta particle emission, the filters use various densities of plastic or even label material.
|
| 27. | Beta particles have much greater penetrating power through tissues than do the much heavier alpha particles.
|
| 28. | The first beta decays are rapid and may release high energy beta particles or gamma radiation.
|
| 29. | The cobalt-60 then decays by the emission of a beta particle plus gamma rays into nickel-60.
|
| 30. | Radium 228 emits beta particles, and is also a concern for human health through inhalation and ingestion.
