good flatness of response. Rh6G is spectrally somewhat flatter in response than RhllO, but it is appreciably (64 times) less sensitive. Surprisingly, RhB, one of the best quantum counters we have observed in methanol, yielded one of the poorest polymer systems; its spectral response is highly dependent on concentration. The only reason for using it in film counters is its wide availability. Ghiggino has, however, reported RhB in PVA (17 wt % ) to be flat to h670 over the range 250-530 nm which makes it currently the only film counter calibrated into the further UV. For the short wavelength region (
