• 論文の詳細を見る

• We measured radioactivity levels of ^137Cs and ^40K in crude drugs imported from Asian countries by γ-ray spectrometry using Ge detector - MCA. Concentrations of ^137Cs in imported crude drugs were very low and close to the limits of detection (about 0.3 Bq/kg dry weight). Furthermore, the type of radioactivity absorbed differed among species. The concentration of ^137Cs was high only in ASIASARI RADIX, whereas ^40K concentrations were high in herb drugs such as PLANTAGINIS HERBA.
