How does high level radiation affect lead acid batteries?

Click For Summary

Discussion Overview

The discussion revolves around the effects of high-level radiation on lead acid batteries, particularly in the context of a scene from the HBO miniseries “Chernobyl.” Participants explore how radiation might interfere with or hasten the discharge of batteries, examining the types of radiation involved and their potential mechanisms of action.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants question how radiation affects lead acid batteries, specifically asking for mechanisms of interaction.
  • One participant emphasizes the vagueness of the term "high level of radiation," suggesting that different types of radiation (beta, neutron, gamma) have distinct interactions with materials.
  • Another participant asserts that high levels around a shut down reactor typically refer to gamma rays.
  • There is a challenge regarding the relevance of neutron radiation, with one participant expressing skepticism about its presence and impact on batteries.
  • One participant introduces the concept of internal short circuits in batteries as a potential failure mode, linking it to temperature increases and safety hazards, although not directly connecting it to radiation effects.
  • A participant speculates on the radiation levels depicted in the series, suggesting they could be lethal within minutes, but remains uncertain about the specific type of radiation involved.

Areas of Agreement / Disagreement

Participants generally express disagreement regarding the type of radiation and its effects on lead acid batteries. There is no consensus on the mechanisms by which radiation might influence battery performance.

Contextual Notes

The discussion highlights uncertainties regarding the specific types and levels of radiation, as well as the lack of detailed mechanisms for how radiation might affect battery discharge. Some assumptions about radiation types and their interactions remain unresolved.

TL;DR
How would high level radiation, like the radiation released at Chernobyl affect a lead acid battery?
During episode 2 of the HBO miniseries “Chernobyl”, the search lights held by the three technicians entering the area beneath the reactor eventually go out from exposure to radiation. If the search lights were powered by lead acid batteries, how does radiation interfere with and/or hasten the discharge of a battery?

What would be the mechanism for any effect at all?

The phrase "high level of radiation" is vague. What TYPE of radiation and by how much? High level of beta is different than high level of neutrons. Each causes different types of interactions with any material.

Without the details, you will not get a specific answer.

High levels for a shut down reactor usually means gamma rays.

At Chernobyl? Neutron radiation, obviously...

Neutrons? I think not.

So you're asking us what a kind of radiation which is hardly there will do to a battery via an unspecified process?
 
I'm not sure if radiation could lead to this, but one of the failure modes of batteries is when the internal separator becomes damaged leading to an "internal short circuit..."
https://www.comsol.com/model/internal-short-circuit-of-a-lithium-ion-battery-34891"During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a compressive shock. A prolonged internal short circuit results in self discharge in combination with a local temperature increase. The latter effect is important because the electrolyte may start to decompose by exothermic reactions if the temperature reaches above a certain threshold, causing thermal runaway with potential health and safety hazards."

Well if we consider the scene from the series, enough radiation to kill an adult man in a couple of minutes.

What type I do not know. I assumed the water they're standing in was contaminated by the core, so contained a mix of decay products.
