Hinkley, P.L. and Heselden, A.J., 1963. AN IMPROVEMENT TO A RADIOMETER FOR FIELD USE. Fire Research Notes 526
ABSTRACT
The radiometer for field use described by McGuire and Wraight (1960) is liable to error owing to reflections from the bevelled edge of the aperture admitting the radiation, on to the mica window and from there on to the receiving element. The present note indicates how this error can be eliminated by blackening the bevel.
