Radiation dosimetry refers to the measurement, calculation and assessment of the ionising radiation dose absorbed by the human body. Accurate dosimetry in radiotherapy is essential to eradicate a cancer, whilst minimising the risk of severe side effects due to the unavoidable irradiation of healthy tissues and organs. In industrial irradiators for sterilisation of medical equipment and pharmaceuticals, the need for accurate dosimetry is governed by two opposing requirements: achieving legal tolerance levels for microbiological contamination, whilst minimising the economic cost.
We provides dosimetry traceable to in-house primary standards for these applications using dedicated facilities such as a clinical linac and high-dose irradiators, as well as specialised Monte Carlo simulation tools. We perform research to develop new dosimetric capabilities following up the rapidly expanding variety of radiotherapy technologies like stereotactic and rotational therapies, as well as for emerging modalities like proton and carbon ion therapy. We contribute to the development of new dosimetric concepts that are closely related to the biological effects of ionising radiation by building and investigating novel micro- and nano-scale dosimeters.

Ultrasound is an important clinical technique and is the second most commonly applied diagnostic imaging method in the India's after X-rays. In the India's, around 3 million obstetric and 8.5 million non-obstetric ultrasound imaging scans are carried out annually, growing at 10% per year.
For obstetric applications, where developing foetal tissue is exposed to ultrasound, safety is critical. Manufacturers must show that their equipment is compliant with existing safety requirements as stipulated by the EU Medical Device Directive or the US Food and Drug Administration reporting requirements.
Therapeutic ultrasound applications are emerging, where exposure is sufficiently high to generate irreversible changes in tissues. This change can be the result of rapid and large increases in temperature and is employed within High Intensity Focused Ultrasound surgical systems used for prostate and uterine fibroid treatments.
Key measurement tools for measuring exposure are ultrasonic hydrophones and radiation force balances. It is important that the performance of these devices is well understood, embodied within appropriate international standards and traceable to primary standards.
Wei Labs has been in the vanguard of researching improved measurement and calibration methods able to address new measurement challenges provided by emerging medical ultrasound equipment; foremost amongst these are extended frequency ranges and elevated power output levels.
