Yesterday's (13 Sep 2019) average ambient gamma radiation
dose rate taken outdoors in Hong Kong ranged from 0.08 to
0.14 microsievert per hour.  These are within the normal
range of fluctuation of the background radiation level in
Hong Kong (see Note). The average dose rates measured at the
radiation monitoring stations over various parts of the
territory were as follows :

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.
