Using cross section formulae from Tan and Ng (1983) and from Hillas (1979) a cascade calculation of neutrino and photon production from a point cosmic-ray source surrounded by matter is performed. The cascade effect on photon production is important in thick matter. In matter more than 100 g/sq cm thick, the gamma-ray production decreases with source thickness above 100 g/sq cm if the primary production is relatively steep, but does not decrease if the production spectrum is shallow. Ultrahigh-energy neutrinos from observed ultrahigh-energy gamma-ray sources are therefore just detectable in a DUMAND-size detector. Nearby sources of lower energy neutrinos (such as a young pulsar in its supernova shell), which are blanketed by thick matter and therefore unidentified electromagnetically, may be detected in underground detectors.
