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 other professionals in radiation physics and radiological engineering. It calculates, among other things, radioactivty 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
       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
       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. Other Uses

The software has also 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. 

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 old hand-held Pocket PCs and year 2003 SmartPhones.  Click on the "Freeware/Rad Pro Desktop" or "Freeware/Rad Pro PDA" buttons above to download those programs.  In these modern times, it is recommended to download the desktop version and use it on portable devices running Window 8.1 or Windows 10.  The desktop version of Rad Pro is available on this site, as well as cumulative probability statistical plotting software and GPS coordinates conversion software. 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.
