摘要：

It is observed that for both UK and Japanese CR-39 detectors the mean diameters of fission fragment and alpha tracks from a Cf-252 source become larger as a result of UV exposure; but in the case of 'UV exposure last' (i.e. Cf + UV) the diameters are larger than in the case of 'UV exposure first' (i.e. UV + Cf). The bulk and track etching rates undergo an increase with UV exposure for the two kinds of CR-39.
