Ambient Gamma Radiation Level in Hong Kong
| 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)

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.
