Radioactive Steel

The video discusses the presence of radioactive elements in modern steel due to nuclear explosions, which increased background radiation levels. It explains the steel production process and how radioactive contamination occurs. The video highlights the importance of low background steel, which is free from radioactive contamination, for specific applications like Geiger counters and medical equipment. It also mentions that such steel can be sourced from World War I battleships submerged underwater.

Discuss the implications of low background steel for certain applications, such as Geiger counters.

Where can one find low background steel that is free from radioactive contamination?
