A study has been carried out at the Prince of Wales Hospital to correlate the DAP
measurements with the TLD measurements. It was found that for each type of
examination, the data correlated very well.
2.2 Protection of members of staff and the general public
The design and mode of operation of X-ray equipment, the nature of the
examination and the techniques used all determine the magnitude of the doses to
both staff and public. The physicist as RPA (or on behalf of RPA) is involved
with:
(a)
The design and layout of X-ray rooms.
(b)
The designation of radiation controlled areas and classified workers.
(c)
The establishment of good working practices.
(d)
The formulation of local rules and systems of works.
(e)
The calibration of radiation measurement equipment.
(f)
The design and execution of dose surveys within the X-ray department.
(g)
The investigation of radiation incidents.
(h)
The provision of a personal dosimetry service.
3.
Applied research and development
The physicist continually seeks to improve existing techniques and develop new
methods. In particular, digital imaging is quoted as an important and fruitful field of
work.
4.
Teaching
The physicist provides teaching and instruction for:
4.1 Radiologists undertaking the examination for Fellowship of the Royal College of
Radiologists and Hong Kong College of Radiologists.
4.2 Radiographers
4.3 Newly enrolled physicist
4.4 Technicians
4.5 Other staff such nurses, usually in aspects of radiation protection
4.6 Training for RPS
