[ RadSafe ] Incidental Radiation Generating Device Leakage Radiation Limits

[Redmond, Randy (RXQ)]

Does anyone know a citation for federal leakage radiation limits for incidental radiation generating devices such as electron beam welders and electron microscopes? I have searched and cannot find any.  As a default, I'm using ANSI N43.3 Exempt Shielded Installation criteria of 0.5 mrem at 5 cm.

Thanks,
