14C measurements of samples containing 5-50 µg carbon allow dating of archeological artifacts or environmental materials with only traces of organic carbon. Furthermore, fossil and non-fossil sources of carbonaceous aerosols can be apportioned using such measurements (Szidat, 2009). The widely-used preparation of solid targets for 14C measurements, however, often remains the weak point of 14C...

Usually, the lack of information cause to be afraid about what we don’t know, imputing to it a greater hazard. On the contrary we face up without fear activities that have a high level of riskiness, but for which we have direct experience. In other worlds the subjective perception of the risk very often doesn’t correspond to the objective and real risk of an activity. In particular the...

Environmental samples in Upper Austria have been measured for ⁹⁰Sr in the year 2005. These measurements were conducted on behalf of the Federal Ministry of Agriculture, Forestry, Environment and Water Management and were part of a project called “Temelin Project”. The aim of this project which started in 1992 is to detect any radiological impact of the nuclear power plant Temelin in...

Fossil fuel CO2 content in the air of a major Hungarian city (Debrecen) was determined using together measurement of CO2 mixing ratio and radiocarbon (14C) content of air. In this project we developed a high precision atmospheric CO2 monitoring station in Debrecen. An integrating sampling system (developed by ATOMKI) was applied for radiocarbon measurements. One sampler was installed in...
