Thermal Neutron Activation Analysis of Vanadium and Manganese in Ginseng using 3.76-Minute Vanadium-52 and 2.58-Hour Manganese-56
Chong Jin Lee, Chong Kuk Kirn, Jin Ha Park
인삼구조에서 미량의 무기성분해함유여부가 기지현상의 일요인이라고 생각되고 이것이 또한 영양학적인 흥미를 모으고 있는 현시 부여삼,금산삼중의 Vanadium 및 Manganese를 열중성자에 의한 방사화분석으로서 정량하엿다. 열중성자류으로서는원자력연구소에 있는 TRIGA MARK Ⅱ 형 원자로를 사용했다. 중성자속이 약 1.28 X 1012 n/cm2/sec 인 곳에 시료를 넣어서 Vandaium은 10분간 Manganese는 5분간 조사한 후 RCL 256 Channel Pulse-Height Analyzer에 2" X 2" Nal(T1)를 연속하여 측정한 결과 1g당 Vanadium은 002ppm, Managanese는 20ppm 정도 포함되어 있음을 알았고 또한 산지에 따라서 다소 차이가 있음을 알았다.

Thermal neutron activation analysis was applied to determine the trace amount of Vanadium and Manganese in Buyo and Kumsan Ginseng. These elements have been regarded to have great nutritional value and one of the indispensable factor in the growth of ginseng. The TRIGA MARK Ⅱ Reactor in Atomic Energy Research Institute was used for the neutron source. The samples were irradiated for 10 minutes for Vanadium and for 5 minutes for Manganese at the neutron flux of about 1.28×1012n/cm2/sec and the RCL 256 Channel Pulse-Height Analyzer connected with 2"×2" NaI(Tl) was used for activity determination. The amounts were about 0.02 ppm for Vanadium and 20 ppm for Manganese, and it was also found that the amounts of the elements were slightly different depending on the kinds of ginsengs.
