Use HPGe detector to test a batch of wipe samples for checking surface contamination for a facility. Due to short half-life of targeted Nuclide, the test must be done without extra delay. Measurement was done by midight.

Calibrate two brand new Alpha/Beta contamination monitors for a department.

Calibrate a Hand-foot contamination monitor.

A set of four sources for teaching are stucked in badly rusted containers. We helped the secondary school to safely get the sources out and provide good containers for storage. Job fishied successfully on Saturday when there's no classes. All sources are ready to serve teaching for Form 6 subject.

Measure radioactivity of Uranium Oxide and Thorium Oxide to support a Secondary School to apply for a Radioactive Substances Licence.

Calibrate a batch of Radiation Area Monitors for a client.

Maintenance for a TLD annealer. All ageing and broken heat isolation materials replaced.

Radioactivity test for a batch of environmental samples, including soil, sand, sea water and grass. To make precise measurements at near background level, sample and liquid nitrogen cooled HPGe detector are placed in lead chamber. It takes more than 10 hours to collect sufficient data for a sample.

Conducted surface contamination test and doserate survey for a batch of packages containing radioactive substances, to support for apply transport permit.

Radionuclide confirmation and radioactivity measurement of an ion chamber to support the client for Radioactive Substances Licence application.

Calibration and selection of TLDs. It was found that the sensitivity for this batch of TLDs (6*4=24) is within +/-5% from their mean reading. They are all selected for further use.

Nuclide identification and activity measurement for a secondary school, supporting RS licence application.
