Can Ionizing Radiation Be Directly Converted to Electricity?

Click For Summary

Discussion Overview

The discussion centers on the possibility of directly converting ionizing radiation into electrical energy without intermediate heat conversion. Participants explore various mechanisms and devices that could facilitate this process, including beta-voltaics and potential applications in nuclear technology.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants inquire about mechanisms for direct conversion of ionizing radiation to electricity, comparing it to how batteries and photoelements operate.
  • One participant discusses the concept of charge separation, suggesting that beta-voltaics could be a relevant technology for this purpose.
  • Another participant raises the issue of fission fragments and their short range in solids, questioning the feasibility of using semiconducting devices for energy conversion from these fragments.
  • Concerns are expressed regarding the accumulation of various chemical species in semiconductors due to fission fragments, as well as the effects of neutron activation and radiation.
  • Some participants mention that alpha particles have a longer range than fission products, prompting comparisons between their respective energy and mass characteristics.
  • There is a discussion about the potential for advanced fusion reactions to yield charged particles that could be harvested using electrostatic fields, although technical obstacles remain.
  • One participant notes the low activity of alpha decays in never-run reactors and discusses the implications of uranium isotopes and their decay rates.
  • Another participant questions how the enrichment of uranium affects the ratio of uranium isotopes and their decay activities.

Areas of Agreement / Disagreement

Participants express multiple competing views on the feasibility and mechanisms for converting ionizing radiation to electricity. The discussion remains unresolved, with no consensus reached on the best approach or technology.

Contextual Notes

Limitations include the dependence on specific definitions of energy conversion mechanisms and unresolved technical challenges related to the proposed methods.

Whatever the method, the basic problem is that the starting point (radiation) is chaotic. This limits the efficiency.

Just a passing thought. Is there any paper somewhere what discusses alpha/beta decay as matter of (laser-like) induced emission?
