Does anyone out there know the correct formulation for sodium
thiosulphate solution widely recommended for I-131 spill neutralization,
and/or a reference for this? I've seen it variously specified as:
0.1 N sodium thiosulfate + 0.1 N sodium hydroxide ( to bring the pH up)
+ 0.1 N sodium iodide
the same as above , except that 0.01 N sodium hydroxide is specified
rather than 0.1 N.
Sometimes the sodium iodide isn't mentioned , so I'm wondering what
purpose it serves.
I'd be grateful for any information that anybody can give.
