(10C) Dose Equivalent Rate
An extract from Appendix A of Neutron Personnel Dosimetry, special publication 25012, 44 pages (July 1987).
Appendix A. Pocket Calculator Programs The listings on the following page are programs for HewlettPackard Series 10 calculators. The first listing, "DOSE EQUIVALENT RATE", is used for solving equations (5) FFDE⒨ = 0.0023×Q÷D² and (6) FFDE⒝ = 0.00954×Q÷D², knowing the source emission rate, Q, and either the free field dose equivalent rate, FFDE, or the distance, D. To use this program, the californium source emission rate, in neutrons/sec, is keyed in and stored in register 1 (STO 1). If the distance is known, it is keyed in and LBL B (f B) will calculate the dose equivalent rate for the bare source; LBL D (f D) will calculate it for the DjOModerated source. If the desired dose equivalent rate is known, it may be keyed in and LBL A will give the required distance from the bare source; LBL C will give the distance from the moderated source. All distances are in cm and dose equivalent rates are in millirem/hour. BEST! SlideRule
