The National Institute for Nuclear, Biological, and Chemical Protection, under the European project 16ENV10 MetroRADON (the European metrology program for innovation and research, EMPIR), has developed unique equipment for the testing of measuring devices at low-level radon activity concentrations. The equipment consists particularly of an airtight low-level radon chamber (LLRCH) with an inner volume of 324 liters; a Rn-222 type RF 5 flow-through source with a Ra-226 activity of 4.955 kBq developed by Czech Metrological Institute within the above-mentioned project; and a pressure vessel as a radon-free air source.

Article Synopsis
- The radionuclide I is a long-lived fission product that decays into Xe through beta-particle emission, playing a vital role as a tracer in both geological and biological studies.
- It is crucial for understanding global circulation and significantly contributes to radiation exposure from nuclear waste in deep geological repositories.
- Recent collaborative research among six European metrology institutes has determined the half-life of I to be 16.14 (12) × 10^9 years, which aligns well with existing data but offers improved accuracy.
