Simple relationship between 26Al production rate and major elemental composition of meteorite samples
production rate 26Al terrestrial age howardite eucrite
2017/4/11
Estimation of 26Al (half-life = 705 kyr) content at the time of meteorite fall is required to calculate the terrestrial age
of meteorites using the 26Al content. Previous studies (e.g., Cressy, 1971;...
Changes in the production rate of secondary aerosol particles in Central Europe in view of decreasing SO2 emissions between 1996 and 2006
secondary aerosol particles Central Europe SO2 emissions
2010/2/21
In anthropogenically influenced atmospheres, sulphur dioxide (SO2) is the main precursor of gaseous sulphuric acid (H2SO4), which in turn is a main precursor for atmospheric particle nucleation. As a ...
Ion production rate in a boreal forest based on ion, particle and radiation measurements
Ion production rate boreal forest ion particle radiation
2009/3/6
In this study the ion production rates in a boreal forest were studied based on two different methods: 1) cluster ion and particle concentration measurements, 2) external radiation and radon concentra...
