Evidence is given that neutrons produced by cosmic radiation produce an important fraction of the residual background of counters used for x4C age measurements. Neutron monitoring is essential in order to check irregular variations of the neutron flux, as for instance produced by solar flares. Durin

A method for estimation of 14CO2 present in blood and tissular samples is described. It is basically based on the introduction of large amounts of a gas mixture (95% O2, 5% CO2) in the samples which serves to remove the CO2 label by gas dilution. The gas phase is later captured in scintillation vial
