Radiation safety:
Although the tritium in a watch, due to the very small quantity, does not pose any substantial hazard to human health, we have to be very careful and watchful. On the one hand, it is because tritium itself is dangerous. On the other hand, it is a professional rule to be careful in dealing with radioactive substances.
During the assembly of GTLS watches, extremely high priority is placed in the enhancement of radiation safety. Heavy investment has been input into our radiation workshop which is now considered the best of its kind in the territory.
Staff are well trained in the handling of GTLS. Every one of them has been individually certified fit for radiation work by the Government of Hong Kong. Every one of them is provided with a personal whole body dosimeter to keep track on their exposure to radiation. The average monthly exposure of each staff is only around 0.20 mSv (Sep 2010) while the allowed limit is 1.67mSv per month.
