A valid point.  I had missed that part.  Could the iridium be in a

dispersible form?  The iridium sources I knew of were small metal pellets,

about BB shot size.

Greetings:



The description of the incident included "...the source drive cable crossed

a high voltage cable resulting in damage to the

radioactive source."



It seems feasible to me that striking an electric arc could have vaporized

some of the source capsule and the iridium.

Melting point of iridium: 2447 degrees Centigrade

Boiling point (Vaporization): 4428 degrees Centigrade



I don't think so ...
