PPase Mee Dr, Lauren #, Donaldson « 2. May 16, 1956 Radiologicel Saspling Progran - te be collected at nenzelep (Kabele, Lobereli, Rongelap Iglanis) and Allinginse Atolls, If possible, the sme kind (species) af specimens as taken on the November ee survey end reported in iWFL-)h3 should be collected. 1. Soil To be ‘collected over a knem area of surface, Recommend a tate plate of one foot or Jonzer on a side be placed on the ground, The total activity per square foot of earth surface can thus be determined as long es the cepti ef the sample is such that it is equel to or exceeds any pertolation of radioactive moleotides. It is recommended that the sampis be divided inte tw deptha ~ the firet to a dapth of 3 to bh inches, ami the second to 6 of S inches, Attention should be paid to the miororelief of the terrain, The samples should ta collected at the same sta~ tions cr locstions as those taken on the Cotober~November 1955 (UNFL-l,3) Survey's 2, Water Both fresh cistern andi sea. 3. Flankton A relstively large sempling ef ccepanuts, plus the other importent foud plavite, 5. Invertebrates Soa cucumber, giant clam, cocoanul crab, rock crab, and spiny lobster, & Fish (oemiverous and carniverous) Nusele, liver, and bone, 7, Birds Musele, bone, liver, and eggs. The Sr-$0 data should be reperted in unite of disintegrations per minute per grea wet weighh of items h, 5, and 5,» % would be helpful in correlating these data with other information to have a calcium analysis made of the same samples and reported in units of activity of Fr=90 per gram of esleium « Simshine Units,
