Author Morinaga, Hiroshi|
Abstract A general survey of the spa treatment at Misasa Spa carried out in February, 1979. The informations the author has gathered may be summarized as follows: 1. The majority of spa visitors was over 60 years old. 2. 47% of spa visitors came to this hot spring for rest and recreation, 43% for the purpose of balneotherapy of chronic rheumatic disorders and after-care. 3. Those who visited Misasa Spa for the first time were 32%, the rest being those who visited this spa over 2 times. 4. The length of time they stay at Misasa Spa for recreation was under 7 days, and for curative treatment was for about 2 weeks.

Title Alternative Ammonium content of Archean rocks of the Superior Province
FullText URL pitsr_049_007_013.pdf
Author Honma, Hiroji| Schwarcz Henry P.|
Abstract Ammonium contents were determined for clastic sediments and associated volcanic rocks of the Kirkland Lake area, Abitibi greenstone- granite belt and metamorphic, migmatitic and granitic rocks of the Ear Falls-Dryden area, English River gneiss-granite belt. The NH(4) centents of Archean volcanic rocks (2700~2710m.y.) are very low (0~6 ppm) and immature argillites have also low contents of NH(4) (27~43ppm). On the other hand, a black shale from the Timiskaming Group (2100m.y.) are rich in graphite and pyrite and contain much NH4 (130ppm), providing a firm evidence of relatively abundant presence of an Archean biota compared with a sparcity of morphological record of Archean fossils. The NH(4) content of the rock mentioned above is about a third of those of the upper Proterozoic sediments and it remains to be established whether it reflects the abrupt break in the evolution of life near the Archean-Proterozoic boundary or not. A considerable amount of NH(4) is inherited by highly metamorphic pelitic gneisses and there may be a possibility for indirect prospection of early life by a study of NH(4) in highly metamorphic rocks of the early Archean. It was also found that the gneissic granitoid has much higher content of NH(4) than the post· kinematic massive granitoid.

Title Alternative Excretion of radon in expired air after bathing and drinking of radioactive hot spring water at Misasa Spa
Author Furuno, Katsushi|
Abstract Radon (Rn) contents in expired air after bathing, exposure in hot-air room and drinking of Misasa radioactive hot spring water were determined using an ionization chamber equiped with vibrating reed electrometer. The results were as follows; 1. Rn Contents in the indoor and outdoor air of Misasa spa were in the range of 0.5-1.0 pCi/ℓ and 0.4-0.7 pCi/ℓ. 2. Rn contents in the expired air of persons living at Misasa spa area and none spa area were 0.4-0.9 pCi/ℓ, 0.6±0.2 (S.D.) pCi/ℓ and 0.1-0.9 pCi/ℓ, 0.5±0.2 (S.D.) pCi/ℓ respectively and no difference of Rn contents was observed in both groups. 3. The highest Rn contents in the expired air of subjects bathed in radioactive hot spring (Rn ; 58.0×10(-10) Ci/kg, watre temp. : 41±1℃.) were immediately after bathing, and the values were 10.8-25.5 pCi/ℓ (bathing for 5 min.), 16.0-27.9 pCi/ℓ (bathing for 10 min.) and 38.8-59.3 pCi/ℓ (bathing for 15 min.) respectively. Rn contents in expired air were reduced to about 1.0 pCi/ℓ during 120-180 min. after bathing. The longer the bathing time and the younger the subjects, the higher Rn contents in the expired air. The biological half-life of Rn in the expired air of subjects after bathing was 42-43 min. 4. The highest Rn contents in the expired air of subjects exposed in hot-air room (Rn in air; 54.3pCi/ℓ, air temp. : 37-38℃., humidity: 40%, staying for 15 min.), and the values were 4.9-7.8 pCi/ℓ, and gradually reduced to about 1.0 pCi/ℓ during 120 min. The bioligical half-life of Rn in the expired air after leaving the hot-air room was 43 min. 5. Rn contents in the expired air of subjects immediately after drinking of radioactive spring water (Rn contents: 596.8×10(-10) Ci/kg, 500mℓ), were the highest, and the value were 28.0-101.5 pCi/ℓ, and reduced to about 1.0pCi/ℓ during 180 min. after drinking. The biological half-life of Rn in the expired air was 40 min.
