Purpose of the 2 nd questionnaire To upgrade the database concerning radioanalytical facilities and abilities To investigate how many laboratories of ALMERA member are implementing the R&D activity concerning NORM To estimate that which type of reference materials will be required in the future To make appropriate decisions concerning training of IAEA fellows, scientific visitors, provision of experts, international projects, characterization of reference materials To give information on analytical capability to MS suffers from emergency event
Questionnaire form Consists of 24 questions including the personnel information of contact person Request all ALMERA member to response to the questionnaire

Comments PT and RM In-Situ Gamma-spectrometry Ra-226, Ra-228, Pb-210 and gross alpha/beta activities in drinking water Air filter, milk and bioassay samples (tissue, blood, urine, etc.) Require more amount of PT sample Provide standards with PT samples PT samples for gamma and alpha/beta should be separated RM for air filter, milk and water for Ra-226 and Pb-210
Comments Questionnaire for analysis cost and time Reporting time and sample size depend on activity level and uncertainty required Analysis cost Detection limit and uncertainty required
Conclusion Equipments Gamma-spec ; 100% LSC/Gas-pro ; ~ 80% Alpha-spec ; ~ 70% 45% (27 labs) accredited in gamma-spectrometry Dominant sample matrix ; soil and water Dominant RM purchased ; soil and milk powder Requests for RM : air filter and bio-samples Request for PT : air filter, Ra-226, gross alpha/beta in DW Middle East, S. America and Asia-Pacific labs are interested in NORM
