SUMMARY

The discussion centers on the hypothetical scenario of how quickly an open-front CRT (Cathode Ray Tube) could harm an average adult human. Participants concluded that the CRT would not kill a person due to its beam current being less than 100 microamperes (uA) and the necessity of maintaining a vacuum for its operation. The consensus is that without a vacuum environment, the human body would not experience boiling blood or any lethal effects from the CRT beam. The conversation emphasizes the importance of understanding the operational principles of CRTs in assessing their potential dangers.

PREREQUISITES
  • Understanding of CRT (Cathode Ray Tube) technology
  • Basic knowledge of electrical current measurements (microamperes)
  • Familiarity with vacuum physics and its effects on the human body
  • Awareness of safety protocols in experimental setups involving electronic devices
NEXT STEPS
  • Research the operational principles of CRTs and their safety mechanisms
  • Study the effects of electrical current on human physiology
  • Explore vacuum technology and its applications in electronics
  • Investigate safety measures for conducting experiments with high-voltage devices
USEFUL FOR

This discussion is beneficial for electronics enthusiasts, physics students, and safety engineers interested in the operational safety of CRT technology and its implications in experimental environments.

The following in only for fun: If one would cut out the front of a CRT, how fast would it kill an average adult human? If the room needs to be filled with a gas, imagine the person wore a diving mask, if the room needed to be filled with acid, imagine there's some kind of protective gel or deep sea suit that would keep the victim alive (until the beam killed him/her), as long as it's not ridiculously expensive (eg 1M$). I suspect this might be an advanced topic, but I was conservative and marked it as intermediate, feel free to change it.

Happy dicking around

Ask a silly question, get a silly answer.
The CRT would not kill you. The beam current is less than 100 uA, to continue functioning, the CRT would need to maintain a vacuum.

There is insufficient volume of vacuum in a CRT, to change the air pressure in the room.

Your blood would not boil, unless you evacuated the room to a vacuum, because you felt sorry for the electrons in the beam.

our blood would not boil
My blood is boiling now.

Good reply by @Baluncore so the thread is done now.
