peer agreement (net): +3blank/blank test Explanation: It is related to ensuring that testing is 'clean'. Part of a laboratory's Quality Assurance procedure. See website: http://www.radiationsafetyacademy.com/labQA.html "Blank A blank sample is the most basic of QC samples. It is essentially a sample of the same geometry, volume, media type, etc. of the unknown samples but has no activity. Blank samples obtain 2 values. First, it allows a minimum detectable activity (MDA) for each sample to be calculated. Background values will vary and are a function of the constituents of the sample. For example, a sample using a 7 mL glass container would have less background than a 20 mL glass container due to the amount of K-40 found in glass. Secondly, blank samples allow the laboratory to ensure their equipment is not contaminated which would yield Type I errors or errors which result in positive counts but are not really radioactive. Blank QC samples are utilized for every batch of samples and come free of charge. If you have samples which are out of the ordinary, please send a similar sample which is known to be free of radioactivity and we will use that as the batch blank."
