発散と吸収をもつ含放射性元素岩石層の外部効果とU-スコープとの関係

抄録

Characteristics of the U-scope Patterns in general and some special characteristics of Simple and Compound patterns by isolated point sources of radioactive substances are almost perfectly solved in the previous paper, -No. 7, Vol. 27, 1958 of the Journal of Applied Physics, Japan-with many illustrations and there a response function η performed an excellent role in the explanation of the constitution of these patterns. However, Diffused or Background Pattern by diffused sources, for example, by outcrops of granitic rocks, and scattered sources, for example debris of stone frag-ments and gravel on the road, cannot be explained simply by the response function mentioned above. To make it possible to solve these complicated problems the following three concepts are introduced:
i) Substitution of equivalent radioactive surface charge on the outcrop for the actual source.
ii) The integral response function Y=∫^2α_-2αηdφ, and
iii) The fundamental formulae for the calculation of responsibility of U-scope for scattered sources of radioactivity.
This way of conducting the analysis is well supported by the outcome of discussions concerning the experiments carried out at Tokai, the Lake Biwa, and at the Bay of Kojima in March of this year.
