Rad Pro Calculator Download

The most accurate and the most comprehensive Complex Number Calculator (and with special features useful to electrical engineering) to compute scientific/mathematical expressions containing real, imaginary and, in general, complex numbers in standard (rectangular) a+bi and polar (phasor) r∠(θ) forms such as

(1/2 + 2i )(3 + 4i) + 3∠(π/4) + sin(i)cos(2 + 3i)^(4 – 2i) / ln(2+i)

Current Version: 3.26, 5/24/2009 (Improved installation package, 6/23/2009) Rad Pro Calculator for Desktop PCs Download Option Page For those needing portability, Rad Pro for Desktop works with Windows 8.1/10 tablets. Results can be viewed in either Decimal, Hex, or Binary by clicking on appropriate buttons. Calculator Pro is a simple.

The calculations can be performed in RAD (radians) or DEG (degrees) mode.

With the best user interface, this comprehensive complex number calculator optionally converts the result or any complex number in standard form to polar and other modular forms and vice versa (long press i or ∠ to see all forms of the calculated result).

The result can be displayed with fixed, scientific and engineering notations.

This exceptionally powerful complex/scientific calculator supports all main mathematical operations (addition, subtraction, multiplication and division) and functions (power, exponent, logarithm, trigonometric, hyperbolic and their inverses, etc.) with real, imaginary or complex numbers as their arguments.

Additionally, this scientific complex number calculator supports the Gamma function, Γ, and the psi function, Ψ, and the zeta function, ζ, with real/imaginary/complex numbers as their arguments.

You can also calculate some quantities used in electrical engineering involving complex numbers, i.e., impedance, by selecting expressions and long pressing Σ.

As the value of trigonometric functions depend on the angle mode chosen, by selecting RAD or DEG the complex number calculator, needless to say, displays the computed values correspondingly. Note that, because many functions of complex numbers are evaluated using the trig functions via Euler’s identity, e^(ix) = cos(x)+ i*sin(x), their values depend on the angle mode selected although they may look non-trigonometric. For example, the value of e^2 is the same regardless of the angle mode selected. However the value of e^i depends on the angle mode because it has the same value as cos(1)+ i*sin(1).
Other complex numbers calculators may not give you the correct results when calculating with complex numbers in DEG mode.
This scientific calculator also lets you do statistics with one or two dimensional real data and do a lot more.

The Center for Radiation Protection Knowledge provides downloadable models, data files, computer codes, and help files that provide ready access to data of interest in the radiation protection of workers and members of the public. This collection includes the models, elemental and radionuclide data, and supporting documentation necessary to describe the behavior of inhaled or ingested radionuclides.

Please refer any technical questions about the models, databases, or documentation to Dr. Keith Eckerman.


Rad Toolbox v. 3.0.0 (5/1/2014)

This toolbox provides ready access to data of interest in radiation protection of workers and members of the public. This package was developed for the U.S. Nuclear Regulatory Commission and is documented in ORNL/TM-2004/27. The software runs on a PC under Windows 98/NT/2000/XP to provide access to the data through a single GUI. The data include dose coefficients for intakes of radionuclides, exposure to radionuclides distributed in the environment, and for exposures to photon and neutron radiation fields. Other supportive data include interaction coefficients for alpha, electron, photon and neutron radiations, nuclear decay data, biological and physiological data, and supplemental information on various topics. The ORNL TM report is included in the download. During the installation elect to ignore any messages regarding file updates. The NRC Rad Toolbox Web page is located at:

DCAL System v. 8.4 (11/1/2006)

DCAL is a comprehensive software system for the calculation of tissue dose and subsequent health risk from intakes of radionuclides or exposure to radionuclides present in environmental media. DCAL was developed for the U.S. Environmental Protection Agency and is documented in ORNL/TM-2001/190. The software runs on a PC under Windows 98/NT/2000/XP. The system includes extensive libraries of biokinetic and dosimetric data and models representing the current state of the art. DCAL maybe used either in an interactive mode or in a batch mode and is intended for experienced users with knowledge of computational dosimetry.
