In order to increase the sensitivity of detectors designed for gamma-ray burst astronomy a number of experimenters have built instruments which incorporate large blocks of plastic scintillators. The performance of this type of detector is compared with much smaller sodium iodide scintillators. A consideration of the burst photon spectrum, sources of background and the basic characteristics of the two detector systems suggests that a sodium iodide detector 125 by 125 by 1 cm in dimension is equivalent in sensitivity to a plastic scintillator 5000 by 5000 by 5 cm in dimension.
