This work was carried out on the basis of the etched pore recognition method published in our work. Eight CR-39 plastic plates were fixed at various distances from the ion beam entry window into a bio-chamber filled with water. Then they were etched, dried and scanned by the computer-MPE-1 microscope system with an integrated video camera. About fifty micrographs were done from each side of the plates and recorded in img-files. The modified code of  inscribed ellipses into the image contours of the found pores and calculated the sizes of their major and minor axes. The definition of reduced pore radius was introduced and a formula was obtained for its calculation. Knowing r, the bulk etching rate of the material and the etching time of the plastic, one can find the depths ... view more»
