About the Section

This section co-operates closely with the Hong Kong Observatory in the radiation monitoring of environmental samples and with the Food and Environmental Hygiene Department in the surveillance of radioactive contamination of foodstuff. To backup the Government's Daya Bay Contingency Plan, the Section is endowed with the responsibility of training the laboratory colleagues to provide uninterrupted emergency service in a nuclear mishap. In addition, the Section analyses samples from the Fire Services Department for classifications under the Dangerous Goods (Application and Exemption) Regulations and provides round-the-clock advisory and on-site investigation services for incidents that involve hazardous chemicals. The Section is also charged with the duty of furnishing scientific support to the Trade and Industry Department and the Customs and Excise Department for the implementation of the Chemical Weapons Convention (CWC) in the Hong Kong Special Administrative Region (HKSAR) as well as the import and export control of strategic commodities.


Responsibilities

The Section is responsible for:

  • Lends technical support to the Hong Kong Observatory in the Environmental Radiation Monitoring Programme (ERMP).
  • Provides professional advise as well as analytical services to the Fire Services Department on the classifications of Dangerous Goods.
  • Provides technical advice to the relevant departments and bureaux regarding the enforcement of the Chemical Weapons (Convention) Ordinance, which provides for the legal basis for the implementation of the CWC in the HKSAR.
  • Provide technical and advisory assistance to the enforcement of the Import and Export (Strategic Commodities) Regulations under the Import and Export Ordinance (Cap 60).

Targets and Key Indicators

Key Performance Measures Relating to the Statutory Testing of Dangerous Goods

Targets #

Testing of Dangerous Goods Targets 2016
(Actual)
2017
(Actual)
2018
(Plan)
Dangerous goods within reporting time averaging 14 working days (%) 96^ 98 98 96

The target is revised from 95 per cent to 96 per cent as from 2017.

Key Indicators

Key Indicators for Statutory Testing of Dangerous Goods

Tests Performed on Dangerous Goods 2016
(Actual)
2017
(Actual)
2018
(Estimate)
Dangerous goods 8,120@ 5,079 5,000

The higher work output in 2016 was due to unforeseen and ad hoc litigation samples.

Key Performance Measures Relating to the Advisory and Investigative Services of Radioactivity Monitoring Samples

Targets #

Testing of Radioactivity Monitoring Samples Targets 2016
(Actual)
2017
(Actual)
2018
(Plan)
Radioactivity monitoring samples within reporting time averaging 12 working days (%) 95 100 100 95

Key Indicators

Key Indicators for Advisory and Investigative Services of Radioactivity Monitoring Samples

Tests Performed on Radioactivity Monitoring Samples 2016
(Actual)
2017
(Actual)
2018
(Estimate)
Radioactivity monitoring samples 5,149 5,132 4,700

For targets where reporting time is mentioned, different samples require different analytical procedures, hence different reporting time. The quoted number of working days required represents an average of reporting time for the different types of samples and test requests within the category, while the target (in percentage) is the total compliance rate of the concerned samples and test requests within a particular category against their respective targets.
