Nuclear track membranes offer distinct advantages over conventional membranes due to their precisely determined structure. Their pore size

shape and density can be controlled intentionally so that a membrane with the required characteristics can be produced. The track etching technology plays a most important role in the production of nuclear track membranes. The effects of pretreatment using UV light illumination on track etching of polycarbonate (PC) track membranes were investigated in this work. PC films illuminated by UV light showed a strong enhancement in the track etching rate. Furthermore

the track etching rate had a linear increase with illumination time. The phenomenon is attributed to the oxygen-assisted photo-degradation through generating new photo-unstable species. In this paper

the conductance measurement is also presented

which is a popular method used in etching technology.
