You will find all sorts of information by searching "Chernobyl radiation effects."  It's looks rather interesting & so I'm going to read it all now.  It gives many different web sites to chose from.

Aircraft structure requires a fail-safe approach to design which is difficult to obtain using fusion welding however welding is used in certain areas such as ducting.\nBest I can do with one sentence.

Precautions\nPowdered metallic vanadium is a fire hazard, and unless known otherwise, all vanadium compounds should be considered highly toxic. Generally, the higher the oxidation state of vanadium, the more toxic the compound is. The most dangerous one is vanadium pentoxide.\n\nThe Occupational Safety and Health Administration (OSHA) has set an exposure limit of 0.05 mg/m3 for vanadium pentoxide dust and 0.1 mg/m3 for vanadium pentoxide fumes in workplace air for an 8-hour workday, 40-hour work week.\n\nThe National Institute for Occupational Safety and Health (NIOSH) has recommended that 35 mg/m3 of vanadium be considered immediately dangerous to life and health. This is the exposure level of a chemical that is likely to cause permanent health problems or death.
