The newly developed Model NF-86 and NF-87 radicchromic nylon film dosimeters were manufactured from the host of nylon

with HPR-CN and PR-CN as radiochromic dye respectively. In this paper the results of the comparative study of NF-86

NF-87 with FWT-60 （a U. S. A. product） dosimeters were described

which show that the main dosimetric characteristics of NF-86

NF-87 and FWT-60 dosimeters were almost the same. The NF-86 and NF-87 can therefore serve as simple

quick and reliable means for routine dose monitoring （ranging 103-105 Gy） in radiation processing.
