Radioactive materials - toggle switches.
Issue 13.
This video is dedicated to such radioactive material as a radioactive toggle switch as part of a project on radiation.
Initially, toggle switches were intended for the military industry, but at some point, toggle switches began to be used on the civilian market, for example, in the shields of trucks, buses, trams.
The radioactivity of toggle switches is due to the fact that a permanent luminous mass based on Radium 226 salts is applied to the end of the rod, which allows the tip of the toggle switch to glow for years without the use of external energy sources. Each rod contains 1-2 μCi of radium 226.
This video contains experiments on measuring the radioactivity of various types of manual and automatic toggle switches.
The video also provides historical information about how later, when manufacturing toggle switches, the permanent luminescent mass based on Radium 226 salts began to be replaced with temporary luminescent mass. Based on this, we can observe a comparative analysis of radioactive and non-radioactive toggle switches, and their distinctive features are also given.
The video also talks about the traditional possible dangers when using such toggle switches.
