Determination of heavy metal profiles in dated sediment cores from Sai Kung Bay, Hong Kong

Cesium-137 intake from food in Hong Kong

Water samples, representing seawater, river water, reservoir water, drinking water, and underground water were studied through gamma-ray spectral analysis. Only gamma emitters in the238U and232Th series and40K were detected. No fission product was detected with specific activity above 0.1 Bq/kg. The present data could be the baseline for future monitoring of the radioactivity released from a nuclear plant being built at a 50-km distance from Hong Kong. The variation of detected specific activities may be due to geological differences and the effect of plants.

Gamma emitters in Hong Kong water

A number of structural analysis and CAD system have been developed for structural design, but engineers only apply general purpose structure analysis program to analyze underground structure,which are inconvenient in using The differences between underground structure and above ground structure are as follows:
