PostersWe provide world-class research, calibrations, specialised measurement services and training for the dosimetry of ionising radiation in cancer therapy, diagnostics and industrial sterilisation for medicine and pharmaceutics.
Proton beams exhibit better dose characteristics than x-rays for radiotherapy.
A new state-of-the-art clinical linac facility was opened in November 2008 at the NPL in addition to the existing research linac facility.
IAEA TRS-398, ICRU Report 78 and earlier recommendations assume that ion chamber perturbation factors in proton beams are unity for all ionisation chamber types.
The Practical Course in Reference Dosimetry run by the National Physical Laboratory is primarily aimed at radiotherapy physicists and would benefit anyone wishing to improve their practical dosimetry techniques.
NPL as a National Measurements Institute has the role of maintaining and disseminating the UK’s primary standards in various fields to the user communities. Being somewhat removed from the end user may on occasion lead to something of a detachment to the consequences if/when that dosimetry chain fails.
Ensuring that radiotherapy doses are safe and effective by using existing detection equipment in a novel way.
IMRT (Intensity Modulated Radiation Therapy) is an advanced form of radiotherapy in which dose is targeted on the tumour volume by the use of multiple beams of radiation from a number of directions.
