Variation of Cs-137 in California Coastal Sea Water

Variation of Cs-137 in California Coastal Sea Water.

Concentration factors for Cs-137 in marine algae from Japanese coastal waters.

Concentration factors (CF: Bq.kg-1 in wet algae/Bq.kg-1 in filtered seawater) for Cs-137 in Japanese coastal algae, were investigated during 1984-1990. Cs-137/Cs(stable) atom ratios were also examined to clarify the distribution equilibrium of Cs-137 in marine algae and sea water. The CFs in marine algae were within the range of 5.4 approximately 92, and the geometric mean of CF was 28 +/- 2 (s...

A Comparison of the Dosimetric Parameters of Cs-137 Brachytherapy Source in Different Tissues with Water Using Monte Carlo Simulation

Introduction After the publication of Task Group number 43 dose calculation formalism by the American Association of Physicists in Medicine (AAPM), this method has been known as the most common dose calculation method in brachytherapy treatment planning. In this formalism, the water phantom is introduced as the reference dosimetry phantom, while the attenuation coefficient of the sources in the...

Chronic Cs-137 incorporation in children's organs.

In Belarus's Gomel region, which was heavily contaminated by fallout from the Chernobyl disaster, we have studied the evolution of the Cs-137 load in the organisms of the rural population, in particular children, since 1990. Children have a higher average burden of Cs-137 compared with that of adults living in the same community. We measured the Cs-137 levels in organs examined at autopsy. The ...

distribution and morphological variation of emys orbicularis in the coastal areas of the caspian sea

the coastal areas of the caspian sea are geographically unique and provide habitats for different flora and fauna. one of the remarkable inhabitants of this area is the european pond turtle, emys orbicularis (linnaeus, 1758), about which very little is known. in our study thirty seven (37) adult males of e. orbicularis have been identified in the golestan, mazandaran, ardebil, and east azerbaij...
