Something about Thoriated Tungsten Electrode Radioactivity Ⅱ

The following article will describe the other part content of thoriated tungsten electrode radioactivity.

Is there a concern to the user?
The risk of internal exposure during welding is negligible in most circumstances since the thoriated electrode is consumed at a very slow rate. During the grinding of the thoriated tungsten electrodes, radioactive dust is created, posing the potential hazard of internal radiation exposure by inhalation or ingestion unless care is taken to control the dust.

What to do with the collected dust particles?
1. Regularly remove the dust generated by grinding.
2. Properly dispose of the dust and spent electrodes in accordance with federal, state, and local regulations.

Summary
Several of the information sources listed indicate that the risk of occupational exposure to radiation during storage, handling, and welding with thoriated tungsten electrodes is negligible where simple precautions are taken. Special care should be taken to control and collect dust from grinding these electrodes in order to prevent a potential ingestion and inhalation exposure to radioactive dust particles resulting from this operation.
