In this paper the accumulative radiation dose of radium-226 in human body for whole life was estimated using a method of directdetecmination of the radium-226 content in bone-ash.The results obtainedfrom 60 samples of bone-ash showed that the average value of the radium-226 concent in bone-ash was 2.1×10~(-14)Ci/g.The values of the radium-226 content for the infant group was obviously higher than that for theadult groups between which no significant difference was found in theradium-226 content of bone-ash.There...

In this paper the accumulative radiation dose of radium-226 in human body for whole life was estimated using a method of directdetecmination of the radium-226 content in bone-ash.The results obtainedfrom 60 samples of bone-ash showed that the average value of the radium-226 concent in bone-ash was 2.1×10~(-14)Ci/g.The values of the radium-226 content for the infant group was obviously higher than that for theadult groups between which no significant difference was found in theradium-226 content of bone-ash.There was no difference between bothsexes.The radium-226 content in different bones was found to be different:the highest level was in costal and spinal bones and the lowest in cavum-bone and bones of limbs.Based on these data the average accumulativecontent of radium-226 in human body was estimated to be about 70 pCiand the dose absorbed by bone for year was calculated to be about 2.5mrad.

本文报道了用直接测定人骨灰中~(226)Ra 含量的方法估算人一生中体内镭的累积辐射剂量。60例样品的测量结果表明,骨灰中~(226)Ra 含量的平均值为2.1×10~(-14)居里/克。婴幼组明显高于成年组;各成年组之间,差异不显著,性别间亦无差异。各骨中~(226)Ra 的含量不同,肋骨、脊椎骨之含量最高,而骨盆及四肢骨中含量最低。据此,估算出人体内~(226)Ra 的平均积存虽为70微微居里,并推算得每年骨所吸收的剂量,约为2.5毫拉德。

The daily variations of the activity of nitrogenesa in nodules of soybean weren't the same in different stages of growth in field condition in 1982-1984. The same trends were found in different years and different varieties. As a rule, the activity of nitrogenese in nodules was low at night and increased gradually at day time. The range of its variation was little in rainy and cloudy day. The average activity of nitrogenase per day decreased by 45 percent, and it increased again fine day. Application of nitrogen...

The daily variations of the activity of nitrogenesa in nodules of soybean weren't the same in different stages of growth in field condition in 1982-1984. The same trends were found in different years and different varieties. As a rule, the activity of nitrogenese in nodules was low at night and increased gradually at day time. The range of its variation was little in rainy and cloudy day. The average activity of nitrogenase per day decreased by 45 percent, and it increased again fine day. Application of nitrogen not only decreased the activity of nitrogenase in nodules, but also changed its daily variation. Correlation analysis showed that the daily variation of the activity of nitrogenase was positively correlated with temperature of soil and accu-mudated radiation of sunshine when the day and night maximum temperature was higher than 25℃ , and it was negatively correlated with them when the day and night minimum temperature was lower than 24℃.The data on second dynamics of the activity of nitrogenase for soybean were obtained by means of correcting the value of its activity which was determined in different stage of growth with the average coefficient of correction for the activity of nitrogenase in different stages of growth.

1982—1984年在白浆土田间小区上,采用乙炔还原法,对大豆根瘤固氮活性进行了日变化动态的研究表明:大豆各主要生育期中,其根瘤固氮活性表现出不同的特征,并在年度和品种间观察到相似的规律。全期中,一般夜间活性较低,天亮后逐渐升高。阴雨天活性明显下降,并变幅缩小。施氮不仅降低活性,同时改变了日变化特征,增大日变幅。相关分析表明,测定日昼夜最高土温小于25℃时,固氮活性日变化同当日土温和太阳累积辐射量之间表现正相关趋势;而昼夜最低土温大于24℃时,则表现负相关趋势。根据日变化资料提出了大豆各生育期根瘤固氮活性日平均值校正系数,利用该系数对相应各期某时刻一次测定的活性值进行校正后,便获得田间大豆根瘤固氮活性季节动态的科学资料。

Gamma-ray irradiation is found to decrease the real part of the dielectric constant, increase the dielectric loss, broaden the loss peak at dielectric relaxation, increase the diffuseness of the phase transition but not to affect the spontaneous polarization P., coercive field E_c and...

The dielectric and ferroelectric properties of ScTaO_4 single crystals as a function of temperature and frequency have been measured before and after gamma-ray irradiation with accumulated doses of 5.0×10~6 and 3.8×10~7 Rontgen. Gamma-ray irradiation is found to decrease the real part of the dielectric constant, increase the dielectric loss, broaden the loss peak at dielectric relaxation, increase the diffuseness of the phase transition but not to affect the spontaneous polarization P., coercive field E_c and the transition temperature T_c appreciably. These effects are attributed to the increased densities of free carriers and imperfections after bombarding the crystals with gamma-rays.

测量了经受累积辐射剂量为5.0×10~6伦琴及3.8×10~7伦琴的伽玛射线辐照前后钽酸钪晶体的介电与铁电性能的温度依赖性和频率依赖性。伽玛辐照使介电常数实部减小,虚部增大,相应于介电弛豫的损耗峰变宽,相变的弥散性提高,但对自发极化P_s、矫顽场E_c及相变温度T_c无显著影响。这些效应可归因于辐照引起的自由载流子增多以及缺陷和不均匀性增加。
