Discussion Overview

The discussion revolves around a claim regarding a radioactive metal that allegedly glows white hot continuously, as recounted by a participant's father who worked for a well drilling company. Participants explore the identity of this metal, its properties, and the implications of its use in oil well operations, touching on aspects of radioactivity, thermal radiation, and potential misconceptions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant recounts a personal experience involving a radioactive metal that glows white hot, questioning its identity and whether it is actually hot.
  • Another participant suggests Cesium-137 as a possibility, noting its radioactivity and applications in medical and industrial fields.
  • A different viewpoint emphasizes that the glow may not be due to thermal radiation but rather secondary emissions, particularly in the context of oil well operations.
  • Concerns are raised about the feasibility of a radioactive source glowing white hot, with estimates of half-lives and the implications of using such materials in a borehole environment.
  • Participants discuss the critical mass of Pu-241 and its implications, with some humor regarding the potential consequences of having such a material in the described context.
  • Questions arise about the size of the container and why it wouldn’t also glow if the material were truly white hot, leading to discussions about thermal dynamics and assumptions about the setup.
  • Some participants speculate that the glow could be due to phosphorescent paint rather than a radioactive source, given the time elapsed since the event described.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the nature of the glowing metal, its identity, and the mechanisms behind the observed glow. There is no consensus on the specifics of the material or the validity of the original claim.

Contextual Notes

Participants note the potential for misremembering events from decades ago, and the discussion highlights uncertainties regarding the definitions and assumptions about the materials and their properties.

Who May Find This Useful

This discussion may be of interest to those exploring topics in radioactivity, geophysics, and the historical context of radioactive materials in industrial applications.

TL;DR
What radioactive metal glows white hot all the time?
1961 My father worked for a well drilling company called, Schlumberger in Lansing MI. One day he told me the company has a radioactive piece of metal that glows white hot all the time we keep it in a cement box in the ground inside a metal box with a lid. Sunday Schlumberger was closed and no one was there my father took me to his work to see the glowing metal. He used a crane to remove the cement lid and another lift to remove metal box lid. He said, we are not suppose to look at it but you can take a very fast 1 second look at it. It looked like it was about 4" diameter 4" long. The company lowers that radioactive metal 1 mile down an oil well shaft and takes readings with test equipment.

What metal will glow white hot all the time?

Will it actually be hot?
 
Physics news on Phys.org
To be used for geophysics, in oil well, oil-water porosity analysis, I would expect it to be a fast neutron, or a gamma source. It would probably be accompanied, nearby, by a slow neutron detector.

A borehole contains water that would not react nicely to a white-hot metal. The "white hot" light would not be black body radiation, it would be a secondary emission of light.

Because it looks white-hot doesn't mean it is white hot.
It is almost certainly not white hot.

To glow write hot under its own internal heat means a very short half life - I estimate 10 years for an alpha source. Multi-kg quantities of such a source would be expensive, dangerous and unnecessary. Besides, how would you lower it down a shaft without melting much of your equipment?

There is one moderately common isotope that will do this: Pu-241. However, because we are not discussing the "Lansing crater", it probably wasn't it.

Jeez, I was going to google 'lansing crater' when it hit me. Time for another coffee.

Okay, I give up...I did just google it, and still do NOT get it.

In the words of Foghorn Leghorn, "That's a joke son. Don't you know a joke when you heard one?"

If you had a chunk of Pu-241 that size, it would also be well above critical mass. And to quote another Warner character "...an earth-shattering kaboom!" And then a big hole where Lansing used to be.

The workplace in question is in Lansing, which you may have missed in the OP. V50 cites the continued existence of the place as evidence that it wasn't a supercritical lump of plutonium.

Thread is reopened while we organize a field trip to Lansing to see if it *really* is still there... :wink:

mixing all the great strips.

At the risk of rerailing the thread, if the material is white hot, why didn't the container glow (at least) red hot?

What size "metal box?" Stefan's Law discussion of undefined assumptions will now begin....

It doesn't really matter (within reason). It's not like putting a hot potato in the box. If this is really generating that much internal heat, it's got to go somewhere. If this is as described, its putting out hundreds of kilowatts minimum. Can't keep that boxed up very long.

Frabjous said:
The glow is probably from secondary reactions with the radiation, not direct thermal radiation.
I really doubt there is that much radiation. If the OP is not misremembering events from 63 years ago, it's more likely phosphorescent paint than anything else.
