一种用作个人剂量测定中子探测器的烯丙基二甘醇碳酸酯（ADC）薄片最近被研究用于在质子是主要辐射的空间中作为宇航员辐射暴露控制装置的应用。我们知道，为了提高ADC对高能质子的灵敏度，在制作过程中加入了某种抗氧化剂，从而导致假径迹的大量增加，从而干扰了自动图像分析仪对质子径迹的自动计数。这清楚地表明，在保持良好表面的同时，制造对高能质子具有足够灵敏度的ADC片材的困难。在这项研究中，我们试图修改制造工艺，以提高对高能质子的灵敏度，而不会导致ADC片的表面状况恶化。我们成功地创造了相当好的产品。
An allyl di-glycol carbonate (ADC) sheet which has been utilised as a neutron detector for personal dosimetry has recently been studied for its application as a device for radiation exposure control for astronauts in space, where protons are the dominant radiation. It is known that the fabrication process, modified by adding some kind of antioxidant to improve the sensitivity of ADC to high energy protons, causes a substantial increase in false tracks, which disturb the automatic counting of proton tracks using the auto-image analyser. This made clear the difficulty of fabricating ADC sheets which have sufficient sensitivity to high energy protons, while maintaining a good surface. In this study, we have tried to modify the fabrication process to improve the sensitivity to high energy protons without causing a deterioration of the surface condition of ADC sheets. We have successfully created fairly good products.
