Synthetic nitrification inhibitors are routinely used with nitrogen fertilizers to reduce losses from agroecosystems, despite having drawbacks like poor efficiency, cost, and entry into the food chain. Plant-derived BNIs constitute a more environmentally conducive alternative. Knowledge on activity of soil nitrifiers is largely based bioassays single Nitrosomonas europaea strain which does not dominant member community ammonia-oxidizing microorganisms (AOM) in soil. We determined several...
Since the double disaster of 9.0 magnitude earthquake and tsunami that affected hundreds thousands people seriously damaged Fukushima Daichi power plant in Japan on 11 March 2011, traces radioactive emissions from have spread across entire northern hemisphere. The isotope iodine 131I was generated by nuclear accident arrived Greece 24 2011. Radioactive is present air either as gas or bound to particles (aerosols). maximum concentrations were measured between 3 5 April In aerosols values...
Indoor radon concentrations were measured in 77 schools of the prefecture Xanthi northern Greece. The arithmetic mean concentration is 231 Bq m−3 with a range between 45 and 958 m−3. Thirty five have above 200 nine 400 From continuous gas measurements school relative higher (958 m−3) was deduced 'true' concentration, defined as during hours presence teachers scholars. for time period about 2 weeks 104 same seven times (700 m−3). Greek International regulations workplaces refer to only annual...
Medical examinations performed on four monks of a monastery in the northern Greece revealed heavy metal contamination. Hair analysis, by toxicological laboratory abroad, indicated, among other, presence uranium. The uranium concentrations determined "Elemental Analysis' indicated level that was about five times maximum value reference range, which has been adopted measuring laboratory. After these diagnostic findings, request 10 monks, determination hair and urine samples means alpha...

A regulatory authority for radiation safety should continuously evaluate and improve the national framework, in line with current requirements standards. In this context, Greek Atomic Energy Commission initiated a series of concerted actions. The dose to population due public medical exposures was assessed. assessment exposure based on measurements radon concentrations dwellings, radionuclide environmental samples, air rates; typical examinations or procedures data their frequency. mean...
Abstract Nitrification is associated with significant losses of fertilizer-derived ammonium from agroecosystems. The use biological nitrification inhibitors (BNIs), in place synthetic (SNIs), holds a great potential to effectively reduce N and conforms the current move towards ecological-intensified agriculture. Knowledge activity BNIs soil nitrifiers limited mostly based on bioassays single Nitrosomonas europaea strain. We determined vitro multiple plant-derived compounds as like (i)...
Abstract The capabilities of electret ion chambers (EICs) to measure mean ambient dose equivalent rates were investigated by performing both laboratory and field studies their properties. First, EICs ‘calibrated’ gamma in the Ionizing Calibration Laboratory Greek Atomic Energy Commission. irradiated with different photon energies from angles. factors deduced (electret’s voltage drop due irradiation terms equivalent). In studies, installed at eight locations belonging Early Warning System...
Following the nuclear accident at Fukushima Daiichi Nuclear Power Plant on 11 March 2011, during period 17 to 25 October a total of 22 Greek citizens were measured after their return Greece. Artificial radionuclides detected in 5 individuals by whole body counter measurements conducted 10 and d commencement accident. Of contaminated individuals, 3 adults 2 children, aged 9 y, who stayed for single day Tokyo. Dose calculations performed assuming that sole exposure pathway was through...
Purpose – Radon is responsible for approximately 50 per cent of public exposure to environmental radiation. The purpose this paper quantitatively assess indoor radon levels in Cyprus. Design/methodology/approach In total, 500 passive detectors were used estimate the areas Nicosia (capital), Paphos, Nisou and Famagusta. A total 240 different private buildings randomly selected above districts two placed inside each building. collected on average, three months following placement. Findings...
The Nuclear Technology Laboratory of the Aristotle University Thessaloniki (NTL-AUTh) and Greek Atomic Energy Commission (GAEC) have a continuous collaboration on indoor radon measurements in buildings since 1999. In present work, existing database was enriched with 590 295 houses 76 38 workplaces. total 1948 974 performed by NTL-AUTh GAEC from 1999 to 2012 8 13 administrative regions Greece are presented discussed.
A prototype shadow-shield whole body counter is used at the University of Ioannina Medical Physics Laboratory as a tool in radiation protection and biomedical research. In this study effect natural airborne radioactivity on measurement quality features was investigated performance improvements were developed. Radon air concentration counting room assessed using electret track detectors over short long time periods, respectively under various ventilation conditions. method based assessment...
