Note

      

    1. From readings taken at various locations in Hong Kong in the
past, the hourly mean ambient gamma radiation dose rate may
vary between 0.06 and 0.3 microsievert per hour. (1
microsievert = 0.000001 sievert = 0.001 millisievert)

    2. Temporal variations are generally caused by changes in
meteorological conditions such as rainfall, wind and
barometric pressure.

    3. Spatial variations are generally caused by differences in
the radioactive content of local rock and soil.

    4. The data displayed is provisional. Only limited data
validation has been carried out.
