Environmental standards of nuclear waste disposal, are determined from the accident victim of exposure data, such as animal experiments and war and nuclear test. They are all in a short period of time of exposure, is the impact data on the human body. As exposure example of the long-term, there is an exposure of local residents such as natural radiation exposure and radiation dose especially large Radium Hot Springs. Low-level radiation of these day-to-day exposure shows that it is clear from the fact of more than 1000 years that there is a health-promoting effects, not harmful. Japan of Radium Hot Springs (Tamagawa hot spring) there is a history of 1200 years. Overseas there is a Karlovarsky kraj hot spring of Czechoslovakia that Madame Curie was built. This hot spring there is a history of about 500 years. In addition, hot spring with mixed low-level radium utility from ancient times of BC 100 years, there is a fact that was not the environment pollution. In other words, from the history of the human race, which has been living under the low-level radiation, for establishing more appropriate environmental standards of low-level radiation emitted from nuclear waste, we investigate the historic hot springs.

Earth is a planet that rotates orbiting the sun, that has a natural nuclear reactor in the center, orbited by the asteroid moon, caused the crustal movement in response to the gravitational pull of the moon, and its constituents is cyclically regenerated in the interior of the mantle. This regeneration cycle has been found to be at least 400 million years, seen from the history of the continent birth. In other words, the earth is a natural nuclear reactor, is a substance recycling plant (natural circulation of the nucleus). Taking advantage of this fact, basic logic is established that rare material discharged to the surface should be circulated to the mantle through the crust by utilizing the laws of natural circulation　after being utilized by humans.　In this paper, we will report on how to do the harmless treatment of radiation waste through the law of natural circulation.

In the development of FRP OCTG at high temperature and high pressure areas, i.e., for over 5,000 meter class deep well or for EOR (Enhanced Oil Recovery), adhesive agent durable to high temperature and designed pressure is strongly required. In this paper, we have newly developed adhesive agent for the bonding of the joint part of FRP pipe under 150℃ level of high temperature, and confirmed that it fulfilled strength retention of GPI Standards (above 80%). Furthermore, we have evaluated the adhesive performance by, simplified tensile test and compared with commercially available adhesives.

Combination of compounding and an additive of the resin called hybrid processing gives us resin which requires the high pressure and high temperature environment of the oil well tubular market. When performance confirmation of this hybrid processing is tested chemically physically, many cost and time should be required. The performance evaluation method which settled this problem is in the density measurement which aimed at a change's of physical properties being revealed by the undiluted solution density and density measurement after indurating. When analyzing a change in 4 digits of density because indurating volume shrinkage of general resin is about 3 %, the purpose performance evaluation precision is obtained.

Radioactive waste treating should be based on the original thinking that stratum convection by the motion of the moon and the earth and their gravity affected on others surface as seen from the universe, since required to be tens of thousands of years thinking. Radioactive waste disposal which take advantage of these natural phenomena is required. First, the treatment plant is in the field that requires a study of the re-engineering geophysical, and a natural phenomenon resulting from the features of the formation of crustal movement should be used as treatment plant of the radioactive waste. Additionally, in our present paper, we propose for the radioactive waste research center installation proposal.

Since the accident of Tokyo Electric Power Company, the food radiation contamination that is a problem of internal exposure of low doses is greatly rumored. However, there is no accepted theory for exposure of low doses, and several different descriptions have been made. An overview of such current situation, along with the review of the theories about the health effects of low-dose radiation, we will propose real food safety.

Radiation is not dangerous to the human body if it is low dose. However, as in the case of Chernobyl and Hiroshima Nagasaki A-bombs, when exposed to sharply higher doses than a certain dose, the risk of carcinogenesis will be higher than those who do not. However, compared to radiation below a certain dose, smoking, excessive drinking, etc., is much more risky in carcinogenesis, so we should try to improve our lifestyle rather than break down radiation.

Recycling of silicon chips discharged in the cell manufacturing process is said to be an urgent issue. In this study, we have succeeded in reforming to high elongation resin by adding a very small amount of silicon nanoparticles. In addition, in order to clarify the principle of the resin modifier, the performance of cured resins were compared with the commercially available silane coupling agent. From the obtained results, the performance of resin modifier was found to be judged by densitometry.
