放射線 檢出機의 國産化開發硏究 : Gas-flow型 比例計數管 Gas-flow type Proportional Countre

In proportional counters the amount of ionization per discharge is a function of the primary ionization as well as of the tube characteristics and operating conditions. This paper described a construction for gas-flow proportional counter and pre-amp with use of domestic propane gas. Using propane gas in this gas-flow counter, the slope of plateau was 2.2%/100V, plateau regions were 4100∼4500V, operating voltage was 4300V and counting efficiency was 11.2%. We found that the possibility of constructing an efficient transisterlized gas-flow type proportional counter using inexpensive domestic propane gas.

Since Mu-Sun Choi's proposition for making guns(1337AD) we have developed many guns. The investigation for casting technique, internal crack and necessity of repairing on th Korean peculiar guns collected at museum of Korean Military Academy and Kyungpook National University including Cheon-Ja-ChongTong made 1555 AD were performed by the Gamma-ray radiography, source of which were 8 Ci, 6 Ci and 3 Ci of Ir-192. The film used were Dupond NDT 75 and 0.03㎜ lead intensifying screen was used by considering photo-density and discrimination.

(ALD) using density functional theory (DFT) calculations and ideal-gas methods; herein, we considered adsorption of tris(dimethylamino)silane (TDMAS) on a hydroxylated SiO2 surface to be the example for our investigation. When the reaction free energy is calculated, the DFT results obtained at 0 K suggest that the dissociation of a hydrogen atom from TDMAS is favorable upon TDMAS adsorption, which is inconsistent with the experimental results where one dimethylamino group is released. The experimental results can be accurately predicted when enthalpy and entropy changes are considered at elevated temperatures, thereby indicating the significance of finite-temperature effects in free-energy changes for solid-gas reactions. We analyze the changes in enthalpy and entropy and find that dimethylamine is a more favorable gaseous product than H2 owing to its larger translational and rotational entropy.

X-ray fluorescence techniques employing radioisotope sources to stimulate characteristic X-ray emission and non-dispersive method of X-ray energy selection and it's measurement are described. These fluorescence analysis was carried out with (Sr+Y)^90 as primary X-ray source. For spectroanalysis, NaI(Tl) scintillation detector, Pules height analyzer, X-ray filter are applied. Pules analysis technique was applied to glass and paint. It appeared very typically as described. Pb-Sn alloy and Na_2WO_4, BaCl_2, CuSO_4, solution were analysed with Al(1mm) filter. Accuracies of the analysed solution were 0.02% for 1-10% CuSO_4, 0.05% for 5-15% NaWO_4 and 0.05% for 2-10% BaCl_2 in counting time of few minute.

The relative intensity of secondary electron emission from various nucleides which were irradiated by Co-60 γ-rays has been measured. The possibility of the quantitative analysis of Pb-Sn alloys has been investigated by measuring the relative intensity of Secondary electron emission from various kinds of Pb-Sn alloys.
