CPYRGH Approved For Release 2000/98'N CERECTE or was not clearly different from that produced by normal individuals, The design of the thermo- luminescent film test resembles that of the test with photographic film, Results of these tests partially confirm the results of the photographic film tests and provide a quantitative basis for some initial measurements, They not only show that during "exceptional vision" a strong unknown radiation is emitted, but also show that normal persons emit a relatively low, unknown radiation as well, (u) For these tests we used American film, made by the Harshaw Chemical Company: 6LiF, 7LiF, CaF, and Chinese film LiF (Mg, Ti). A thermoluminescent dosimetric analyzer produced by the Beijing Synthetic Apparatus Plant (Model FL-369) was used for evaluating results. TESTS OF UNKNOWN RADIATION WITH A BIODETECTOR The greatest disadvantage of photographic and thermoluminescent film tests is their failure to show kinetic response (changes in time), so that there is no way to study the delicate time specificity of unknown radiation. Both the biodetector and the light-quanta detector can demonstrate kinetic responses in a test system, but the various types of biodetectors provide more possibilities for experimentation. We have already used a set of simple biodetectors for measuring bioelectric changes in a plant leaf vein (Figure 4). Yet, because the main component of the biodetector is i * a living system (a plant leaf), we cannot expect that the system has sufficient stability. Nevertheless, because the degree of sensitivity obtained from this method is significant, and because it is relatively widespread and easy to operate, it will certainly arouse the interest of many researchers, * See Zhao Yongjie, Xu Hongzhang, et al., "Biodetector Experiments on Human Body, Radiation Physics," Psi Research, Vol. 1, No. 1. pp. 77-84 (March 1982), 28 Approved For Release 2000/4al N-GLADS 9 BF AE1D00400320001-8
