Special efforts must be made to keep the volume of waste as low as possible. E. Contamination Control Control of contamination aboard the research vessels is of vital importance to maintain cleanliness for research groups studying natural levels of radionuclides. Swab tests must be conducted in all areas where radionuclides are used or stored. The isotope vans are usually equipped with a simple liquid scintillation counter that should be used for obtaining immediate results. The results of these tests, including those for blanks, should be sent via Fax to the WHOI Safety Office as soon as obtained.
Any contamination detected by the swab tests requires immediate decontamination by the user.
Any spills or accidents involving radionuclides must be reported immediately to the Chief Scientist and the Master. Upon completion of the cruise, a detailed report of the incident, and the corrective measures taken, must be submitted to the IUC by the user. In general, use of radioactive material on these vessels will be restricted to the isotope van. Upon completion of the cruise, the van must be cleaned completely. This includes removal of duct tape and tie-down materials, scouring of sinks, and cleaning of refrigerators.
