Remarks

1. From readings taken at various locations in Hong Kong during the period 1987-2010, the background ambient gamma radiation levels may vary between 0.06 and 0.30 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. Quality control has not been applied to the above data and the values may be affected by noises.
