title = "On a radiochromic dye dosemeter",
abstract = "Radiochromic dye dose meters made of polyvinyl butyral (PVB) with hexa(hydroxyethyl)pararosaniline cyanide (HPR-CN) as the radiation-sensitive element are being developed and investigated at Ris{\o}. This report summarizes the present results and outlines plans for further research on this dose meter. Currently the response is found to be almost stable after irradiation, but recalibr?tion of a given batch is needed every 3-6 months because of changes in response characteristics with age. Under typical laboratory conditions, the temperature coefficient is found to be about +1X per degree Celcius and the relative humidity coefficient +(0.4-0.5)X per percent change in relative humidity. The response drops ~ 15% when the dose rate is lowered from 1.1 Gy/sec to 0.2 Gy/sec.This research is supported by IAEA through research contract No. 2051/RB, and this report constitutes the progress report for the period November 1979 - October 1980.",
