In this context, there appeared a need to develop a dose-optimised route finding method for firefighting rescue vehicles, which includes the development of a real-time decision support measurement and evaluation system. This determines and visualises the radiation exposure of possible routes in a tested area. The system inside and outside of the vehicle measures the ambient dose equivalent rate, the gamma spectra, and also the airborne radioactive aerosol and iodine levels. The method uses gamma radiation measuring NaI(Tl) scintillation detectors mounted on the outside of the vehicle, to determine the dose rate inside the vehicle using the previously recorded attenuation conversation function, while continuously collecting the air through a filter and using an alpha, beta, and gamma radiation measuring NaI(Tl)+ PVT + ZnS(Ag) scintillator to determine the activity concentration in the air, using these measured values to determine the effective dose for all routes and all kinds of vehicles. The energy-dependent shielding effect of the vehicle, the filtering efficiency of the collective protection equipment, and the vehicle’s speed and travel time were taken into account. The results were validated by using gamma point sources with different activity and energy levels. The measurement results under real conditions and available real accident data used in our simulations for three different vehicles and pedestrians proved the applicability of the system. During a nuclear accident based on our model calculations, the inhalation of radioactive aerosols causes a dose almost an order of magnitude higher than the external gamma radiation caused by the fallout contamination. The selection of the appropriate vehicle and its route is determined by the spectrum that can be measured at the accident site but especially by the radioactive aerosol concentration in the air that can be measured in the area. In the case of radiation measuring detectors, the shielding effect of the carrier vehicle must be taken into account, especially in the case of heavy shielding vehicles. The method provides an excellent opportunity to reduce the damage to the health of accident victims and first responders during rescue operations.

E technológiák kapcsán fel-merült bizonytalanságok azonban még korántsem teszik lehetővé azok széles körű használatát. Erre már számos olyan tudományos és szakmai közlemény is rámutatott, amelyek a geomérnökség környezeti, meteorológiai következményeit elemzik. Tekintettel az energiaágazatnak és az iparbiztonságnak a környezeti fenntarthatóságban betöltött alapvető szerepére, indokolt megvizsgálni a geomérnökségnek az energiaágazat, illetőleg az energetikai rendszerek működésére és biztonságára gyakorolt lehetséges hatásait is. The applicability of geoengineering for climate change management and environmental sustainability has been the subject of investigations for years. However, the uncertainties which have arisen in connection with these technologies do not yet allow their widespread use. This has already been pointed out by numerous scientific and professional publications that analyse the environmental and meteorological consequences of geoengineering. Given the fundamental role of the energy sector and industrial safety in the environmental sustainability, it is reasonable to examine the possible effects of geoengineering on the operation and safety of the energy sector and energy systems.
