Hong Kong Observatory fully resumes normal monitoring of radioactivity in air

26 May 2011

On 12 May, the Observatory began resumption to normal air sampling and radiological analysis by phases (see details in the following Press Release: http://www.weather.gov.hk/press/D4/2011/pre20110511e.htm).

For the past 2 weeks, air sampling at Yuen Ng Fan has reverted from daily to weekly monitoring, while sampling at King's Park continued at a daily basis.

For more than 40 days since 14 April, no artificial radionuclides have been detected in the air in Hong Kong. In view of the relatively stable situation, all air sampling and radiological analyses will be carried out according to normal schedule starting today (26 May). Air sampling at King's Park will revert to weekly monitoring.

The Observatory will continue to release radiation monitoring data on its website. These include hourly environmental gamma radiation data from the Observatory's network of 10 radiation monitoring stations, as well as results of radiological analysis of other samples, including sea water, land soil and rain.

The Observatory will closely monitor the situation in Fukushima, as well as radiation levels in other places, and will step up monitoring again if necessary.
