Chapter 4 CONCLUSIONS Examination of data indicates the followingconclusions: 1. For surface bursts with yields from fo 5 Mt, and for a een airburst, initial-gamma radiation is of littfe"mifitary significance tounprotectedpersontiél as compared with thermal and blast damage. 2. The amountof residual-radiation exposure is a function of the fission yield. 3. The curves of initial-garnma exposure versus distance obtained from Project 2.1 data vary from corresponding TM 23-200 curves. The field data falls below predictions at longer ranges and is greater than predicted at shorter ranges. This difference between predicted and field data increases with increasing yield. , 47
