Medica-Plus: a Micromegas-based proof-of-concept detector for sub-becquerel tritium activity assessment at the service of oncological research

To fulfill needs in oncological research a new Micromegas detector has been developed to follow radiolabelled drugs in living organisms at the single cell level. This article describes the proof-of-concept of such a detector and compares its ability to detect and assess sub-becquerel \tritium~activities with a commercial $\beta$-imager
