The report contains radiological safety instructions for the use of a 100 millicurie Cesium 137 source in the Lane-Wells Nuclear Sediment Density Meter. These instructions were prepared in compliance with the U. S. Atomic Energy Commission, Division of Materials Licensing regulations for radioactive byproduct materials. Procedures are provided for handling and storage of the source under shipboard operating conditions. Design drawings of the source and shield assemblies, and source handling tools courtesy of Lane-Wells Company, Houston, Texas are provided with radiation profiles of the source in the shielded and unshielded positions. Radiation dosage on the surface of the meter ranges from 50 to 146 milliroentgens per hour in the shielded position and 2600 milliroentgens per hour in the unshielded position. At a distance of four feet perpendicular to the meter, these values range from 0.5 milliroentgens per hour in the shielded position to 10 milliroentgens per hour in the unshielded position. Author
