[ RadSafe ] Gamma emissions of Co-60 ?

[Frank Helk]

Hi folks,

I've read or heared somewhere, that the main gamma rays emitted from Co-60 (1173 keV and 1333 keV) thru the decay process are always emitted in 
opposite directions. I'm somewhat puzzled about that, and I can't find any source about that behaviour.

Does anybody out there have a hint ("true", "false", literature source if true ?)

Best regards

	Frank
