LABORATORY FOR DETECTION OF IRRADIATED FOOD<br />

Activity profile: Detection of irradiated food. European standards (CEN) adapted as analytical<br />

methods to be routinely used in the Laboratory are based on electron paramagnetic resonance<br />

(EPR/ESR) spectroscopy, pulsed photo-stimulated luminescence (PPSL) and thermoluminescence<br />

measurements (TL). The research work is focused on the development of these methods as well as<br />

on validation and implementation of other detection methods as gas chromatographic determination<br />

of volatile hydrocarbons in fats, DNA comet assay (observation of single cells destruction) and<br />

statistical germination study. The quality assurance system is adapted in the Laboratory in agreement<br />

with the PN-EN 150/IEC 17025:2001 standard and fully documented. Laboratory possesses Accreditation<br />

Certificate of Testing Laboratory AB 262 issued by the Polish Centre for Accreditation valid<br />

from 25.10.2002 to 25.10.2006.<br />

optical stimulated luminescence (OSL) system.<br />

Application: Detection of irradiated foods containing silicate minerals, e.g. spices, vegetables shrimps<br />

tc, research work on irradiated foods.<br />

• Fluorescence microscope<br />
