[en] During operation of accelerators the air of irradiation rooms, gets activated by neutrons. The radioactive gases and aerosols contribute to the radiation exposure of persons in the neighbourhood. Recommendations are given how emissions and therefore the radiation burden can be minimized. The recommendations are applied to the exhaust air installations of a compact-cyclotron and a mini-cyclotron. 8 figs. (Author)

[en] This Decree prescribes the licensing for the release of gaseous wastes from nuclear installations as well as the technical supervision of such operations. It does not apply to the transport of radioactive effluents which is governed by the regulations on the transport of dangerous goods. (NEA)

[en] The handling of ground gas generation is one of the critical challenges of landfill management. The Victorian Environmental Protection Agency guidelines for landfill management seek to “ensure no safety or environmental impacts are caused by landfill gas. (EPA Victoria, 2015).” Since gas generation is inevitable within any landfill handling organic materials, a set of well worked methodologies have been developed for dealing with it safely, including energy generation, flares and bio-filters. However, fugitive emissions, those not accounted for by gas mitigated strategies, are not unknown or unexpected. Consequently, leeway is provided to landfill operators however fugitive emissions must be contained below a set of action levels (EPA Victoria, 2011) and the EPA must be notified of exceedances within 24 hours. Importantly, the landfill licensing guidelines, stipulates that “all practicable measures must be undertaken to achieve the landfill action levels” (EPA Victoria, 2016) which largely puts the onus on the operator to go above and beyond the minimal requirements to ensure compliance. In short, reportable and actionable gas levels are well described… the next question is, how often should measurements be taken? (author)

[en] A device is proposed for trapping gases escaping during a failure of the primary circuit of a nuclear power plant. A bag is airtightly connected to the bubbling depressurization system. In the case of an escape the steam/gas mixture partly condenses in the depressurization system and the uncondensed radioactive gases will fill the bag from which non-active air is forced out. This method may be used in technological processes in which harmful gaseous products are generated with an overpressure of 10 Pa and more. (J.C.)
