 Detailed programs for utilizing the … Texas Instruments SR-52 programmable pocket calculators for calculating the shielding capability of buildings by the DCPA standard method.

 Although the "Standard Method" of calculating the protection factor of a shelter fs well understood by qualified FSAs, it is seldom used in practice. Reasons for this are both numerous and controversial, but the fact remains that it is seldom used in practice.
 The availability of programmable pocket type calculators in 1974-75 presented a new situation. It seemed, at that time, that the pocket computer might work in calculating the PF by the "Standard Method." Consequently, a feasibility study was undertaken to decide this issue.
 The feasibility study was comleted in December 1976 and a favorable report written and its recommendations were used as a basis for establishing the objectives of this project …
 It was decided to prepare the initial programs on the Hewlett-Packard Model 97 (desk top model) … These programs had to undergo significant changes before they would work on the Texas Instrument calculator. These changes were made for the TI Model SR52.


 Appendix C contains the listings for all the programmed cards … the TI … listing for its programs are simply shown on the SR 52 coding form …
