1st International comparison measurement on assessing the diffusion coefficient of radon.

abstract：:Dosimetric monitoring and protection of the personnel involved into interventional procedures is one of the key issues nowadays, yet doses received by their brains were left without rigorous consideration so far. The paper is the fast track of the results of the pilot study of possible magnitude of operator's doses wi...
