There is a growing need in health and climate research for high-quality radon observations. A variety of radon monitors, with different uncertainties, operate across global networks. Better compatibility between the measurements is required. Here we describe a novel, portable two-filter radon monitor with a calibration traceable to the International System of Units, and demonstrate the transfer of a traceable calibration from this instrument to a separate monitor under field conditions.

Sardinia Region promoted a plan to protect the population from exposure to radon gas. Communication activities are ancillary to develop the whole monitoring and risk identification, a work in collaboration among professionals, a dialogue with policy-makers and the community in general, to develop awareness and prevention. Strengths, weaknesses and lessons learned are shown.

Radon gas is the largest source of public exposure to naturally occurring radioactivity. Radon can also be used, as a tracer to improve indirectly the estimates of greenhouse gases important for supporting successful GHG mitigation strategies. Both climate and radiation protection research communities need improved traceable low-level atmospheric radon measurements. The EMPIR project 19ENV01 traceRadon started to provide the necessary measurement infrastructure and transfer standards.

Tritium concentration analyses were performed on groundwater samples collected in wells in the south part of Treviso city, to correlated the presence of tritium with the young age of the water recharge. The results show strong differences in recharge by recent rainwater which reflect the variation in permeability of the sediments. The aquifer analyzed was vulnerable to prolonged drought periods which could produce a worsening of water quality, consequently limiting water availability.
