How does high level radiation affect lead acid batteries?

In summary, the conversation discusses the impact of high levels of radiation on lead acid batteries and how it may lead to an internal short circuit. The type and level of radiation are unclear, but it is suggested that it could be enough to kill an adult man in a short amount of time. The specific mechanism of how radiation could affect a battery is also discussed.

TL;DR Summary
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.
 

1. How does high level radiation affect the performance of lead acid batteries?

High level radiation can have a significant impact on the performance of lead acid batteries. It can cause a decrease in capacity, reduced efficiency, and increased self-discharge rates. This is due to the radiation damaging the electrodes and electrolyte, resulting in decreased conductivity and increased internal resistance.

2. Can high level radiation cause lead acid batteries to fail?

Yes, high level radiation can cause lead acid batteries to fail. When exposed to high levels of radiation, the electrodes and electrolyte can become damaged, leading to a decrease in battery performance and ultimately failure. Additionally, radiation can also cause corrosion of the battery's components, further contributing to failure.

3. How does radiation exposure affect the lifespan of lead acid batteries?

The lifespan of lead acid batteries can be significantly reduced when exposed to high levels of radiation. The damage caused by radiation can accelerate the natural aging process of the battery, leading to a shorter lifespan. In extreme cases, the battery may fail completely, rendering it unusable.

4. Can lead acid batteries be shielded from high level radiation?

Yes, lead acid batteries can be shielded from high level radiation. Lead is an effective shielding material for radiation, and lead acid batteries already contain lead in their construction. By increasing the thickness of the lead casing or using additional shielding materials, the battery can be protected from radiation exposure.

5. Is it safe to use lead acid batteries in areas with high levels of radiation?

It is generally not recommended to use lead acid batteries in areas with high levels of radiation. While the batteries can be shielded, prolonged exposure to high levels of radiation can still cause damage and decrease battery performance. It is best to use alternative battery chemistries that are more resistant to radiation in these types of environments.
