An extract from PF Calculating by DCPA Standard Method, Defense Civil Preparedness Agency, Technical Report, DCP01-76-C-0325, JAN 78, 95 pgs.

ABSTRACT
 Detailed programs for utilizing the Hewlett-Packard (Hp) 67 and 97 … programmable pocket calculators for calculating the shielding capability of buildings by the DCPA standard method.

INTRODUCTION
 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) …
…
CARD PROGRAMS FOR EQUATIONS
 It was apparent from the feasibility study that a major consideration in the final developed project would be the number of program cards required for any PF calculation. The more cards used, the larger and more Cumbersome the process. Therefore efforts were focused upon programming cards that would solve the equations for all the charts …
 Appendix B contains 11 listings for a 11 chart equations programmed on HP cards.
…
PROGRAMS FOR THE METHOODOLOGY
…
 Appendix C contains the listings for all the programmed cards. In the case of the HP chips the listing was made from the printer on the HP 97 model. To make these listings more readable they have been annotated …

ENJOY.

BEST!
