It is the object of the present paper to investigate in more detail the nature of uranium radiation and the electrical conduction produced. As most of the results obtained have been interpreted on the ionization-theory of gases which was introduced to explain the electrical conduction produced by Röntgen radiation, a brief account is given of the theory and the results to which it leads.
In the course of the investigation, the following subjects have been considered:
1. Comparison of methods of investigation.
2. Refraction and polarization of uranium radiation.
3. Theory of ionization of gases.
4. Complexity of uranium radiation.
5. Comparison of the radiation from uranium and its compounds.
6. Opacity of substances for the radiation.
7. Thorium radiation.
8. Absorption of radiation by gases.
9. Variation of absorption with pressure.
10. Effect of pressure of the gas on the rate of discharge.
11. The conductivity produced in gases by complete absorption of the radiation.
12. Variation of the rate of discharge with distance between the plates.
13. Rate of recombination of the ions.
14. Velocity of the ions.
15. Fall of potential between two plates.
16. Relation between the current through the gas and electromotive force applied.
17. Production of charged gases by separation of the ions.
18. Discharging power of fine gauzes.
19. General remarks.
