In case of Radiological and Nuclear (R/N) emergencies, fast and timely detection of the individual absorbed dose levels is of paramount importance for sorting out unaffected subjects from those requiring medical intervention. Different physical techniques have been used for the dose assessment from the radiation damage induced in biological tissues or in common-place materials. In this work Photo-Stimulated Luminescence (PSL) technique was applied to inexpensive personal objects that people usually have in their bags/pockets (cigarettes, snacks, paper handkerchiefs, banknotes). The literature states encouraging results obtained with such objects; the novelty of this work is represented by the instrument proposed for the analyses: a low cost, portable system usable in situ for rapid tests (about 60s) on samples as received. The preliminary results obtained with cigarette tobacco and salty snacks are reported here. The study was supported by NATO Science for Peace and Security Programme, grant No. G5684.

放射線及び原子力（R/N）緊急時には、影響を受けていない対象者を医療行為を必要とする対象者から分別するために、個人吸収線量レベルを迅速かつ適時に検出することが最も重要である。これまで、生体組織や一般的な物質で誘起される放射線障害による線量評価には、さまざまな物理的手法が用いられてきた。本研究では、光励起ルミネッセンス（PSL）法が人々が普段バッグ/ポケットに入れている安価な身の回り品（タバコ、スナック菓子、ティッシュペーパー、紙幣）に適用された。文献には、このような品物で得られた有望な結果が記載されている。この研究の目新しい点は、分析に提案された計器、すなわち、受け取った状態のサンプルでの迅速な試験（約60秒）に原位置で使用できる可搬型システムが表している。ここでは、タバコと塩味のスナック菓子で得られた予備的な結果を報告する。本研究は平和と安全保障のためのNATO科学プログラム、助成金番号G5684の支援を受けた。
