We present the results of an analysis of measurements of the beta-decay ratesof Ag108, Ba133, Eu152, Eu154, Kr85, Ra226, and Sr90 acquired at thePhysikalisch-Technische Bundesanstalt from 1990 through 1995. Although thedecay rates vary over a range of 165 to 1 and the measured detector currentvaries over a range of 19 to 1, the detrended and normalized currentmeasurements exhibit a sinusoidal annual variation with amplitude in the smallrange 0.068% to 0.088% (mean 0.081%, standard deviation 0.0072%, an 11{\sigma}rejection of the zero-amplitude hypothesis) and phase-of-maximum in the smallrange 0.062 to 0.083 (January 23 to January 30). In comparing these resultswith those of other related experiments that yield different results, it may besignificant that this experiment, at a standards laboratory, seems to be uniquein using a 4{\pi} detector. These results are compatible with a solarinfluence, and appear not to be compatible with an experimental orenvironmental influence. It is possible that Ba133 measurements are subjectalso to a non-solar (possibly cosmic) influence.
