Interstellar and circumstellar matter is known to be strongly irradiated by cosmic radiation and several types of cosmic ray particles. The effects of irradiation on simulated interstellar and circumstellar matters such as $rm CaCO_3$, $rm MgCO_3$, $rm SiO_2$ and $rm AI-2O_3$ are investigated.In particular, thermoluminescence spectra after gamma-ray and neutron irradiation are compared carefully. It is shown that the thermoluminescence after neutron irradiation appears significantly in the wavelength of blue region. Furthermore, some problems around them are investigated.In this year, we have published one of the summaries of our research for thermoluminescence after irradiation on simulated cosmic-matter in Planetary and Space Science. Further, we have studied irradiation effects on simulated cosmic-matter. Especially, we have studied on irradiation effect of crystalline silicate by making use of LINAC. However, some further problems remain because of some instability of recently revised LINAC. We have also researched for possible problem concerning to formation of minor elements and fine structure through possible irradiation of cosmic rays, or further fundamental structure of cosmic particles.

众所周知，星际物质和情节物质被宇宙辐射和几种类型的宇宙射线颗粒强烈辐照。辐射对模拟星际和情节事务的影响，例如$ caco_3 $，$ $ rm的mgco_3 $，$ $ rm sio_2 $和$ $ rm ai-2o_3 $的影响，尤其是在Gamma-ray和中子辐射后进行了热度发光光谱。结果表明，中子照射后的热发光显着出现在蓝色区域的波长中。此外，研究了它们周围的一些问题。今年，我们在《行星和太空科学》中对模拟宇宙摩擦的辐射后发表了热发光研究的摘要。此外，我们研究了对模拟宇宙 - 物质的辐照效应。特别是，我们通过利用Linac研究了晶体硅酸盐的辐照效应。但是，由于最近修订的Linac的某些不稳定，仍然存在一些其他问题。我们还研究了可能通过可能辐射宇宙射线或进一步的宇宙颗粒基本结构来形成次要元素和精细结构的可能问题。
