	Studies of radiation damage equivalence have been
	conducted in four different neutron environments by using
	silicon transistors with gain-bandwidth products covering
	the range from 1 MHz to 2 GHz and power ratings covering
	the range from 200 mW to 115 W. The neutron environments
	were obtained from two TRIGA reactors, a fast-burst
	reactor, a 14-MeV generator, and a Californium 252
	fission source. Experimentally, damage factors were
	obtained by comparisons of changes in the reciprocal of
	the common-emitter dc gain as a function of measured
	fluences. The damage factor was the slope of the
	resulting curve. Corrections were made for the fraction
	of total damage associated with gamma radiation effects.
	The ratios of the slopes of the data from the different
	irradiation facilities give an indication of spectral
	differences among the facilities. These ratios do not
	appear to be strong functions of collector current or of
	the transistor type. The experimental data were compared
	with theoretical calculations of displacement damage as
	defined by the damage curves of Messenger and of Holmes.
	The ratio of 14-MeV generator to fast-burst reactor
	damage is less than predicted theoretically; the ratio of
	fast-burst reactor to TRIGA reactor is higher than
	calculated. Uncertainties in the parameter and dosimetry
	measurements could account for some of the observed
	differences, but the uncertainty in the spectra content
	of the reactors is probably the major contributor.
