1. General Site Description

Rad Pro Calculator online performs many nuclear calculations that are useful to the health physicist, radiological researcher, radiochemist, radiation safety officer, health physics technician (HP) and radiation physics professional. It calculates, among other things, radiation safety units conversions (SI and US customary) and gamma emitter dose rate and activity. 

2. Other Calculations

       1:    Gamma emitter shielding equations (with or without buildup)
       2:    Beta emitter dose rate and activity
       3:    Dose-rates for x-ray machines and devices
       4:    Grams of plutonium (Pu) and uranium (U) from activity (specific activity)
       5:    Isotope radioactive decay, timed decay and half life equations
       6:    Bremsstrahlung x-ray calculations for beta interactions
       7:    Uranium fuel loading ratios
       8:    Uranium enrichment from U-234 and U-238 lab data for environmental levels of uranium
             (also works well for uranium fuel enrichment and U enrichment in nuclear waste)
       9:    Inverse Square Law calculations for electromagnetic energies
      10:   Minimum detectable concentration and contamination (MDC aka MDA) for counters and                     scanners (includes LLD and critical level calculations)
      11:   ALARA calculations for dose and job planning 

3. Site Details

The software has recently gained popularity with nuclear professionals in medical engineering, medical physics and other nuclear medicine disciplines.  Included are the most common isotopes at nuclear power reactors and government and private research facilities.  Also included are isotopes for nuclear medicine use (such as P-32 (32P), Tc-99m (99mTc), FDG / F-18 (18F) and other positron emitters used in PET scanning.  To request another isotope, use the "Contact Us" button above, under "Rad Pro Information" button.  The x-ray machine/device calculator allows the choice of empirical data or the use of known x-ray tube output.  The x-ray shielding equations are the same ones used in the gamma isotope calculator so the shielding effectiveness is conservative (press the "About" button on the X-Ray page for further explanation).   

4. Online Calculator Access and Desktop/PDA Freeware Downloads

To access a web based Rad Pro Calculator, use the "Online Calculators" menu button at the top of each page and search through the tree menu.   Also on this site are downloads for freeware nuclear desktop applications and software for hand-held Pocket PCs and SmartPhones.  Click on the "Freeware/Rad Pro Desktop" or "Freeware/Rad Pro PDA" buttons above to download those programs. A desktop version of this site is available, as well as cumulative probability statistical plotting software and GPS coordinates conversion software. Two versions of Charles Hacker's Radiation Decay (aka RadDecay or Rad Decay) software are also available with automatic installers.

The software was originally called NukeWorker Calculator.    It can calculate dose and dose rates for many radioactive isotopes such as Co-60 (gamma and beta mR/hr and mrad/hr), Sr-90 (beta mRad/hr), P-32 (beta Gy/hr), Cs-137 (gamma and beta mSv/hr and mGy/hr), Ra-226, Am-241, C-14, H-3, S-35 and I-192. The gamma dose rate calculator also calculates shielding using all of the latest data from NIST (attenuation coefficients) and ANSI (buildup factors). The user may calculate many nuclear equations that are often time consuming and tedious. These calculations are a time saver to the health physics, radiation protection or radiation safety engineer professional (such as RSO). Use this website to perform radioactive decay and half-life equations. Convert radiation activity, dose equivalent abd absorbed dose units such as Gray (Gy), Bequerel (Bq), rad, rem, dpm, sievert (Sv), Curie (Ci), as well as mGy, mrem, mR, mSv, MBq, kBq, mrad, krad, mCi, uCi, pCi and nCi. This site contains three uranium calculators (uranium enrichment calculations, uranium fuel loading calculations and uranium grams calculations). Calculate the distribution of uranium isotopes in new nuclear fuel. The site is used by many government employees in the DOE, NRC and EPA. The user has a choice between the online calculator and a desktop radiation calculator. This site is supported by and featured by NukeWorker. The calculations on this site may be useful to the person assessing cancer risks. This site contains inverse square law calculations for the radiation protection student. The equations on this site are useful to professionals doing remediation and decommissioning projects (D&D, DandD) at nuclear power plants and USDOE sites. Isotopes included on this site are H-3 (3H), Be-7 (7Be), C-11 (11C), C-14 (14C), N-13 (13N), N-16 (16N), O-15 (15O), F-18 (18F), Na-22 (22Na), Na-24 (24Na), P-32 (32P), P-33 (33P), S-35 (35S), Cl-36 (36Cl), Ar-41 (41Ar), K-40 (40K), K-42 (42K), Ca-45 (45Ca), Sc-46 (46Sc), Sc-47 (47Sc), Cr-51 (51Cr), Mn-51 (51Mn), Mn-52 (52Mn), Mn-54 (54Mn), Fe-55 (55Fe), Fe-59 (59Fe), Co-55 (55Co), Co-57 (57Co), Co-58 (58Co), Co-60 (60Co), Cu-61 (61Cu), Cu-62 (62Cu), Cu-64 (64Cu), Cu-67 (67Cu), Ni-63 (63Ni), Zn-62 (62Zn), Zn-65 (65Zn), Ga-64 (64Ga), Ga-67 (67Ga), Ga-68 (68Ga), Ge-68 (68Ge), As-72 (72As), As-74 (74As), Se-72 (72Se), Se-75 (75Se), Br-75 (75Br), Br-77 (77Br), Kr-81m (81mKr), Kr-85 (85Kr), Kr-85m (85mKr), Kr-87 (87Kr), Kr-88 (88Kr), Kr-89 (89Kr), Rb-81 (81Rb), Rb-82 (82Br), Rb-83 (83Br), Sr-85 (85Sr), Sr-89 (89Sr), Sr-90 (90Sr), Sr-92 (92Sr), Y-88 (88Y), Y-90 (90Y), Y-91 (91Y), Zr-89 (89Zr), Zr-95 (95Zr), Nb-94 (94Nb), Nb-95 (95Nb), Mo-99 (99Mo), Tc-96 (96Tc), Tc-99 (99Tc), Tc-99m (99mTc), Ru-97 (97Ru), Ru-103 (103Ru), Ru-106 (106Ru), Pd-103 (103Pd), Pd-109 (109Pd), Rh-105 (105Rh), Ag-108m (108mAg), Ag-110m (110mAg), Cd-109 109Cd), In-111 (111In), In-115m (115mIn), Sn-117m (117mSn), Sb-122 (122Sb), Sb-124 (124Sb), Sb-125 (125Sb), Te-123m (123mTe), Te-127 (127Te), Te-129 (129Te), Te-132 (132Te), I-122 (122I), I-123 (123I), I-124 (124I), I-125 (125I), I-129 (129I), I-131 (131I), I-132 (132I), Xe-127 (127Xe), Xe-131m (131mXe), Xe-133 (133Xe), Xe-133m (133mXe), Xe-135 (135Xe), Xe-135m (135mXe), Cs-130 (130Cs), Cs-131 (131Cs), Cs-134 (134Cs), Cs-137 (137Cs), Ba-131 (131Ba), Ba-133 (133Ba), Ba-137m (137mBa), Ba-140 (140Ba), La-140 (140La), Ce-139 (139Ce), Ce-141 (141Ce), Ce-144 (144Ce), Sm-145 (145Sm), Sm-153 (153Sm), Tb-149 (149Tb), Gd-153 (153Gd), Pr-144 (144Pr), Pm-147 (147Pm), Eu-152 (152Eu), Eu-154 (154Eu), Eu-155 (155Eu), Dy-165 (165Dy), Ho-166 (166Ho), Er-169 (169Er), Yb-169 (169Yb), Tm-170 (170Tm), Tm-171 (171Tm), Lu-177 (177Lu), Ta-178 (178Ta), Ta-179 (179Ta), Ta-182 (182Ta), Re-186 (186Re), Re-188 (188Re), W-187 (187W), W-188 (188W), Ir-192 (192Ir), Ir-191m (191mIr), Os-191 (191Os), Os-194 (194Os), Au-198 (198Au), Tl-201 (201Tl), Pb-203 (203Pb), Pb-210 (210Pb), Pb-212 (212Pb), Pb-214 (214Pb), At-211 (211At), Bi-210 (210Bi), Bi-210m 210mBi), Bi-212 (212Bi), Bi-213 (213Bi), Bi-214 (214Bi), Po-210 (210Po), Rn-220 (220Rn), Rn-222 (222Rn), Ra-223 (223Ra), Ra-224 (224Ra), Ra-226 (226Ra), Ra-228 (228Ra), Ac-225 (225Ac), Ac-227 (227Ac), Ac-228 (228Ac), Th-227 (227Th), Th-228 (228Th), Th-229 (229Th), Th-230 (230Th), Th-232 (232Th), Pa-233 (233Pa), Pa-234 (234Pa), Pa-234m (234mPa), U-232 (232U), U-233 (233U), U-234 (234U), U-235 (235U), U-236 (236U), U-238 (238U), Np-237 (237Np), Pu-238 (238Pu), Pu-239 (239Pu), Pu-240 (240Pu), Pu-241 (241Pu), Am-241 (241Am), Cm-242 (242Cm), Cm-243 (243Cm), Cm-244 (244Cm) and Cf-252 (252Cf).   The x-ray device calculator includes gypsum wallboard (drywall) as a shielding material.  X-ray tube filters include beryllium (Be), Be plus aluminum, aluminum, copper and lead filters.  For now, the empirical calculations are only for constant potential (continuous wave) (Kv or kVCP) generators.  Pulse or pulsating potential (kVP) data was sparse.  N
