      irradiation and absorption
    Scientists can use the equations to predict the inhomogeneous irradiation and absorption of direct and diffuse solar radiation and UV-radiation at surfaces of the human body.
          
      radiation absorbed
    The samples under study are heated by gamma radiation absorbed in the adiabatic mode.
          
    Additional problems arise as only about 11% of the solar radiation absorbed by the planet reaches the surface, and most of it is taken up in the clouds at altitudes of 60-70 km.
          
    Therefore, the fraction of the radiation absorbed by the disk wind in this case is considerably smaller and can be comparable to the effect from the puffed-up inner rim only at an accretion rate of the order of or higher than 10-6M⊙yr-1.
          
    It is shown that squeezed states of such vibrations can result in microwave-frequency modulation of the optical radiation absorbed at electronic transitions in quantum dots.

    The influence of exposure of pregnant rats to a single injectionof HTO on the development of functions of nervous system in their offspri-ngs was observed by electro-encephalography and examination of swimmingfunction and the changes in body weight of offsprings were also observedunder same condition of HTO exposure.The experiment was performed in 15female rats and their 120 offsprings.For rats of group A,HTO was intrap-eritoneally injected at the lst day of gestation(in the embryo period)andfor rats of group B,at the 13th day of gestation(in the fetus period)andthe dose of HTO injected was enough to keep a concentration of HTO of1.85 MBq(or 50μCi)per l mL of body water in animals.The doses abs-orbed during exposure in utero to HTO by offsprings were estimated to be0.59±0.01 Gy and 0.56±0.01 Gy,respectively.The results show that incomparison with controls,there are no marked changes in basic electro-encephalogram for offsprings of 18,32 and 36 days old in both groups A and B with the except of a decrease(especially obvious in group A)ofresponsibility to rhythmical light stimuli and to sound stimuli in 32 and 36day old offsprings;that the swimmig function for 8 and 18 day old offspringswas obviously reduced in same content in both groups;and the frequency ofretardation in development of body weight for offsprings was increased at 5,8 and 18 days old in both groups(rather obvious in group B).

    以脑电图、游泳机能和体重为指标,观察了氚水单次注入妊娠大鼠后对其仔鼠神经系统机能及体重发育的影响。实验是在15只雌性大鼠及其所产的120只仔鼠分 A、B、C 三组进行的。A 组大鼠于妊娠第1d(胚胎期),B 组大鼠于妊娠第13d(胎儿期)经腹腔注入氚水,使动物体水氚放射性浓度达到1.85MBq/ml(50μCi/ml)。A、B 两组仔鼠在子宫内受氚水照射的吸收剂量分别为0.59±0.01和0.51±0.01Gy,C 组为对照组。结果表明,A、B 两组仔鼠第18,32和36天龄基础 EEG 与对照组相比无明显改变,但32和36天龄仔鼠 EEG 对节律光刺激同步化反应和对声刺激的阻抑反应皆受到阻碍,A 组尤为明显。A、B 两组仔鼠第8和18天龄时游泳机能明显受阻,两组受阻程度相同。第5、8和18天龄时两组仔鼠体重发育不良的发生率皆有所增加,B 组更为明显。

    The depth dose distributions and uniformity of beta radiation fields from anatural uranium slab in equilibration were measured using a tissue equivalentextrapolation chamber and film dosimeter. The chief advantages for calibration ofenviromental dose instrument or survey meter and personal dosimeter, for routinemonitoring in terms of directional dose equivalent and superficial individual doseequivalent were summarized. Finally, the values measured agree well with that oftheoretical calculation.

    本文总结了天然铀(+子体)块作为β射线外照射吸收剂量刻度用参考标准源的7个优点。用组织等效外推电离室测量了天然铀照射聚乙烯材料时的深部剂量分布。用裸露胶片测量了源中心轴上空气中浅表吸收剂量随源到探测器距离的变化,以及不同距离处垂直于中心轴的平面上剂量场的均匀性。指出了按照ICRU第39号报告提出的定向剂量当量H’(0.007)和浅表个人剂量当量H_?(0.007),用这种源刻度环境或工作场所监测仪表和个人剂量计时应注意的问题。最后把测量值与根据天然铀及其主要子体的复杂能谱进行的初步理论估算值进行了比较,符合较好。

    Objective Production site development and alterations of early pulmonay fibrosis were studied. Method Single irradiation was made at right thorax of rats with 0,15 and 30 Gy of γ irradiation, respectively.The rats were divided into three groups which were sacrificed 1,3,5 months post irradiation.Hydroxyproline in lungs was measured by biochemical method.Pulmonary type I and Ⅲ collagens were measured by polarization method.Distribution of angiotensin Ⅱ (AⅡ) in pulmonary tissues was displayed by immunohistochemical method. Results Extent of pulmonary fibrosis relatively increased with irradiation dose and time elapse after irradiation.Ratio of type I to type Ⅲ collagens increased with increasing fibrosis.Proliferating collagen fibers mainly came from fibroblasts of pulmonary bronchial and arteriolar adventitia,and extended into pulmonary parenchyma.Meanwhile,type I collagen substituted for type Ⅲ collagen in interstitium of pulmonary alveoli.AⅡ was positive for fibroblasts and macrophages in pulmonary interstitium. Conclusion Irradiation can stimulate fibroblasts in interstitum proliferation,and type I collagen substitutes for type Ⅲ collagen.Expression and synthesis of AⅡ in interstitium may promote the course of pulmonary fibrosis.
