So,based on the data of 39 soil profiles in different areas of red soil,this paper analyzed the relationship between()~(137)Cs content and the composition of soil particles using statistical methods.

Land use/cover changes affect both redistribution of 137Cs inventory and 137Cs depth distribution in soil profile.

The basis of the ~(137)Cs technique and the uses of this technique to investigate the sedimentation rates of suspended sediments deposited on river floodplains are reviewed to identify the sources of sediments and to research the sediment-associated contaminates on river floodplains.

Based on the methodology of study on water, soil environmental capacity and mass conservation theory in a system, the concept and model on sediment environmental capacity for ~(137)Cs in Daya Bay are developed.

This paper represents the study of migration of~(90)Sr and~(137)Cs in a kind of aerated zone soil.

The results show that: (1) the wall of the waste disposition pit has a good capacity to stop leaking of the radioactive liquid; (2) 226 Ra and 232 Th have almost the same characteristic when they migrate with water through soil; (3) the migration velocity of 137 Cs in soil is about 1.

This review describes research progress of several methods of 137 Cs removal from acidic high level liquid waste such as precipitation, volatilization, solvent extraction, inorganic ion exchange.

In this paper, the results of the 90 Sr and 137 Cs contents in biologic samples and the natural U in soil samples obtained in a joint effort by fourteen environmental radiation laboratories in the Chinese environmental protection system were analyzed and compared.

The accumulation characteristics of the 7Be and 137Cs show that 7Be inventories in sediment cores of Lake Erhai and Lake Hongfeng (and Lake Baihua) are (237±73) Bq/m2 and (783±44) Bq/m2, respectively.

The study emphasized on the effects of 137 Cs on spring wheat and transfer factors in soil\|wheat systems.

Three distinct \{\}\+\{137\}Cs peaks (formed at 1964, 1975, 1986, respectively) are recognized in the sediment core of Chenghai Lake.

The Cesium-137 profile distribution and soil erosion rate were studied in the Yangwa watershed of loess plateau of south Ningxia.

Cesium-137,a fallout product of atmospheric nuclear tests,is strongly adsorbed to soil particles and can be used to trace soil movement.

Cesium-137 and GIS(Geographical Information System) technology was used as main methods and several natural conflux slopes in gullied area of Loess Plateau were taken as studying objects,a preliminary study from a microcosmic point of view on the influences of different terrain factors was made.
