Risø B3 radiochromic dosimeter film

The Risø B3 radiochromic dosimeter film, manufactured by Tesa in Hamburg, is designed for high-precision measurement of absorbed dose distributions in industrial radiation processing. It is particularly well-suited for use in installation qualification (IQ), operational qualification (OQ), and routine dose mapping of irradiated products.

With a dose response range from 5 to 100 kGy, the B3 film covers a wide spectrum of applications. Dose evaluation is performed either using a flatbed scanner in combination with the RisøScan software or by spectrophotometric analysis—both methods delivering high spatial resolution and reliable results.

The Risø B3 dosimetry system complies with ISO/ASTM 51275:2004, the standard practice for using radiochromic film in radiation processing dosimetry systems. Its stable and reproducible response ensures an effective method for verifying dose delivery and assessing dose uniformity across products.
