However, higher efficiency devices were in the development process utilizing bidirectional beta sources.
2.
Betacels utilized Pm-147 beta sources that were combined with custom designed silicon p-n junctions.
3.
All I need now is a link to a websight where I can find a list of beta sources.
4.
This effect is greater with material of high atomic numbers, so material with low atomic numbers is used for beta source shielding.
5.
So I suppose you could take your beta source and place the detector some known distance from it and measure the amount of radiation.
6.
In all those applications, 227 Ac ( a beta source ) is merely a progenitor which generates alpha-emitting isotopes upon its decay.
7.
A radium beta source was placed at the center of a circular condenser consisting of two silvered glass plates spaced 0.25 mm apart and charged to about 500 volts, set in a homogeneous 140 Gauss magnetic field.
