If you have any questions related to the survey, please contact us. We might add your request to the FAQs below if your question is relevant for other users.
For questions and answers related to public exposure, please refer to this FAQ document.
Answer 1: The data submitted should be signed off by the national contact person (NCP), including name, institution and contact details (email/phone) to facilitate any feedback. Please, indicate contact details of additional experts that helped. Accessing the questionnaires and submitting the collected data is only possible when you are registered on the UNSCEAR online platform.
Answer 2: The collected data should be signed off by a person who represents official national authorities. NCPs are officially nominated by their countries to coordinate the data collection and submission and are required to registered on the UNSCEAR online platform.
Answer 3: Please submit the filled out questionnaires / spreadsheet “Essential information” by 30th of November 2017 and the detailed questionnaires / spreadsheets by 30th of June 2018. UNSCEAR is interested in all national responses even if the information is incomplete.
Answer 4: UNSCEAR uses this data for its global assessment of radiological exposure. If precise numbers are not available, countries are asked to make best estimates extrapolated to 100% of the national activities.
Answer 5: The uncertainty estimate could be based on a standard uncertainty analysis (e.g. Standard Deviation at 1 Sigma, which provides a level of confidence of approx.68%). If there was no analysis conducted, an uncertainty single value (not range) should be chosen, best fitting one of the following criteria:
< 25% if the data are based on a representative survey or on a national database or register (educated or good guess).
25-75% if the data are not based on a representative survey but the data are expected to represent the practice of your country (vague to good guess).
> 75% if the data are based on a small and no representative sample (vague guess).
Answer 6: The Number of occupationally exposed workers should be listed by sector. The Uncertainty should be filled in as instructed in the question 5. The Monitoring coverage should provide the percentage of workers covered by routine monitoring programs in your country. If all workers are monitored on routine basis, indicate 100%.
Answer 7: The data gathered will be used for the extrapolation and it is recognized that countries might find it hard to acquire such information in a short notice, although they are encouraged to do so.
Answer 8: The UNSCEAR Health Care Levels are based on the number of physicians per population in the countries and is an important piece of information to improve the accuracy of the global estimate of radiological exposure from medical uses of radiation.
Answer 9: The UNSCEAR assessment gathers as much data as possible to analyse the extent of radiological exposure. This approach requires detailed information provided by countries.
Answer 10: UNSCEAR needs to further develop the extrapolation model in order to be prepared for the evaluation of the detailed questionnaires.
Answer 11: Yes, participation in the survey - even if a country doesn’t have all information - is important for UNSCEAR’s evaluation. Some data is better than no data.
Answer 12: More instructions on how to fill in the information are given in the questionnaire’s spreadsheet 'Introduction', in the cells 'comment field', which become visible when placing the mouse cursor on the title cell.
Answer 13: The essential information questionnaires (simplified data) on medical and occupational exposure ask for the most recent available data. The detailed questionnaires on medical exposure also collect the most recent data while the occupational exposure questionnaire collects data from 2003 until 2014 (each year in a separate sheet).
