【摘要】 本文介绍了在296×10¹⁴Bq⁶⁰Co辐照装置上辐照300t大蒜的辐照工艺研究。用Fricke剂量计测定分布剂量,从而选择合理的辐照方案。大蒜放置在距源中心110cm的弧线上,辐照大蒜的平均吸收剂量100Gy,最大吸收剂量160Gy,最小吸收剂量67Gy,辐照均匀度D_max/D_mix=2.4。日加工量16t,辐射源的使用效率5％。本文还描述了辐照剂量在各个方向的分布。更多还原

【Abstract】 The irradiation process for 300 tons of garlic on a 2.96×1014Bq Co60 radioactive source was studied. From results of dose measurements with Fricke dosemeter, optimum mode of irradiation was selected. Garlic was placed 110 cm away from the source center. The mean absorbed dose was 100 Gy, with Dmax 160Gy and Dmin 67Gy. The processing capacity was 16 tons a day and the efficiency of the source was approximately 5%. The dose distribution along every directions was also discussed.更多还原
