摘要：

Orange-red uranium-glazed dinnerware was found to emanate Rn-222 to produce an average of less than 0.1 Bq Rn-222 decay per piece, which should have no associated health risks. Comparison of Rn-222 emanation to Ra-226 in glazes (measured by alpha spectrometry) indicated inefficient emanation (<5%) of Rn-222, consistent with the low radon levels observed and with the presence of Rn-222 progeny in glazes. These studies also showed that reagent grade uranium compounds may emanate measurable Rn-222.
