Abstrakt:	The ideal method for monitoring the environment should be rapid, low cost, and sufficiently sensitive to detect any changes caused by nuclear facilities during their normal operation. A combined initial preparation step for environmental samples in the detection of organically bound tritium (OBT) and radiocarbon (14C) makes the analytical process quicker, while the use of a Parr 1121 large-capacity oxygen vessel, which allows the combustion of around 20 g of dried organic sample, reduces the detection limits for both parameters. The method was validated with inter-laboratory intercomparisons for the OBT and a comparison with the official values of environmental samples for the 14C. [ABSTRACT FROM AUTHOR]
