The entire deck of Searaven was wood except for the area over the mufflers and near the bow. Scrubbing seemed effective on the wooden deck' planking only during the first few days of scrubbing. After this the top of the planking was bare. The sldes and lower portion were inaccessible. Removal of decking on 10 August allowed cleaning rust and contaminated paint beneath, thereby lowering readings. Since Searaven was scraped and repainted with only one coat of paint before arriving at Bikini. there were few areas of heavy paint. Removal of light paint and rust by scrubbing did have an initial effect of greatly of Searaven's loweringradiactivity.Themajority superstructure had become so rusted through age and exposure during war patrols that removal of all rust was Impossible. On several steel castings, which could be cleaned bare. the readings were 0.1 to 0.2 R/24 hours below surrounding areas.No decontamination work was done below decks since all compartments were originally below 0.1 R/24 hours (or soon became so as topside readings dropped) (Reference 4).
