DOSE CALCULATIONS FOR USS LST-1146.
Shot ROMEO wasthe only test that resulted in fallout on LST-1146. The fallout was

relatively light and probably did not alter routine crew duties onboard the ship. The daily film
badge dose is calculated by multiplying the contributions to exposure, both topside and below
(from table 3.8), by the appropriate time-averaged shielding factor or apportionment factor.
Contributions from each source are summed and convertedto a film badge dose. Cumulative film
badge doses through 31 May 1954, by which time dose accrualfalls below | mrem per day, are
given in table 4.8.
