2) Sodium thiosulphate (Na2S2O3)

    Personally, I never thought of KI (or NaI) as being light sensitive although I know doped NaI is used to detect gamma rays. However, from what I've been able to read on the Internet, KI does have some sensitivity to light. Sodium thiosulfate apparently does not.
