DOSIMETRY

A smarter dosimetry system

and mitigation technology

THE IMPORTANCE OF DOSIMETRY

Radiation dosimetry in the field of health physics is the measurement, calculation and assessment of the ionizing radiation dose absorbed by an object, usually the human body. This applies both to ingested or inhaled radioactive substances and to irradiation due an external source of radiation. 

The effective dose, expressed in sievert (Sv) is intended to represent the stochastic health risk, which for radiation dose assessment is defined as the probability of radiation-induced cancer and genetic damage. One sievert carries with it a 5.5% chance of eventually developing fatal cancer based on the linear no-threshold model.

INNOVATION IN THE FIELD OF DOSIMETRY

BAQ, together with HEPIA is developing an innovative system to measure, assess and mitigate the effective dose due to airborne radioactive particulate matter. Beyond the field of radon mitigation, the system will works in most situations in which radioactive particulate gets dispersed in the environment, in particular workplaces. One example is the stone cutting industry for construction, another example is metal cutting as part of decommissioning of nuclear power plants.

HEPIA, the Geneva School of Landscape, Engineering and Architecture, is one of the six Geneva-based institutions attached to the universities of applied sciences of Western Switzerland (HES-SO).
