Radiation shielded Go-Pro camera sent through electron beam irradiator

Click For Summary

Discussion Overview

The discussion revolves around a radiation-shielded Go-Pro camera that was exposed to an electron beam irradiator. Participants explore the effects of radiation on the camera, the nature of the electron beam source, and potential electromagnetic interference affecting the camera's performance. The conversation includes technical inquiries and challenges regarding the specifications of the camera and the context of the exposure.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants express curiosity about the radiation exposure levels (measured in rads) that the camera experienced.
  • There are questions regarding the nature of the electron beam source and whether it could be influenced by external factors like a transformer causing electromagnetic interference.
  • One participant suggests that the camera's grey-out could be due to the amplifier being overloaded rather than radiation effects.
  • Technical specifications of the "radiation shielded" GoPro unit are requested, particularly concerning its EMI immunity testing.
  • Some participants express frustration over the lack of provided technical details and the expectation for others to seek out this information.
  • There is a mention of a "read more" tab in the video description, which some participants believe should have been referenced earlier.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the nature of the effects observed in the video or the technical details of the camera. Disagreements arise regarding the expectations for information sharing and the interpretation of the camera's performance.

Contextual Notes

There are unresolved questions about the specific characteristics of the electron beam source and the environmental conditions during the exposure. The discussion also highlights differing levels of familiarity with the video platform used to share the camera footage.

TL;DR
Digital camera sent through radiation-emitting machine.
A radiation-shielded go-pro camera was sent through an electron beam irradiator.

You can see the effects that the radiation has on the camera in the video.

I wonder how many rads it was exposed to.

Interesting. What is the nature of the source? I'm sort of wondering if there might be something like a massive big transformer there providing intense magnetic field variation. Maybe the speckles just before the max exposure are radiation, and the complete grey-out is the amplifier in the camera getting overloaded by being beside a huge transformer. Just wildly guessing.

In the atmosphere? What kind of e-beam source shoots across 1-2 meters in the atmosphere?

Agreed, it could be EM interference. I see that kind of response often in high-level EMI susceptibility testing. We use antennas and big power amplifiers to blast the test devices.

@ElliotSmith -- do you have any technical specs for this "radiation shielded" GoPro unit? What level of EN 61000-4-3 (radiated EMI immunity) has it been tested to?

I don't know any technical details, try reading the video description.

I have no idea what that means. Is there some secret symbol in the YouTube video that I'm supposed to click on to get to some "more details" page? And TBH, I don't appreciated you trying to put more work on me to try to figure out information that you should have posted in the first place...

There is a "read more" tab underneath the video. Anyone familiar with youtube knows this.

I guess that's the fundamental problem. I'm out.

And anyone familiar with PF knows that, as @berkeman has already said, you don't ask other people to do work you should have done in the first place in order to help you.
