Lab-Grown Diamond Technology Poised to Revolutionize Radiation Dose

A Lab-Grown Diamond the Size of a Thumbnail Could Unify Radiation Measurement in Medicine

It sits on a fingertip. Four millimetres by four millimetres, half a millimetre thick, sealed inside a sliver of light-blocking polyethylene because even ordinary room light would throw off the readings. The device looks, for all practical purposes, like a fragment of nothing much. But this particular fragment of lab-grown diamond is roughly 1,250 times smaller than the radiation detectors routinely used in hospitals, and it can measure doses wi…

Lab-Grown Diamond Technology Poised to Revolutionize Radiation Dose

In a landmark advancement poised to revolutionize radiation dosimetry, researchers from Tokyo Metropolitan University, in partnership with Tohoku University and the tech company Orbray Co., Ltd., have engineered a diamond-based detector that challenges existing paradigms in medical radiation measurement. The team’s innovative approach harnesses heteroepitaxial diamond materials, lab-grown with atomic precision, to create a compact yet highly sen…
