Mail-order alanine reference dosimetry service for radiation processing

There is a growing demand for gamma and electron beam radiation processing of medical, pharmaceutical and food products with even more precise dose delivery, often customised to meet specific sterilisation requirements.

Irradiation sterilisation plants with ever faster turn-round times and higher capacities require the highest standards in validation and quality control. In addition, EN/ISO Standard 11137 and US FDA GMPs demand dosimetry traceable to recognised national standards when sterilising by irradiation.
