Spectrum Key File for Introductory VRF - $95
To request a key file, please send an email to Support@SnakedanceScientific.com and attach the spectrum file that you would like to analyze. After payment is received, a key file for that spectrum will be sent to you by email. Key files are not licensed and can be used by anyone without fee. Key files work with all versions of VRF. For example, an instructor can give a copy of the same key file to all of his students, year after year, for them to use with their own licensed copy of Introductory VRF.
Note: A key file has the same name as the file to be analyzed, but has a file extension of "+KE". The key file must be placed in the KeyFiles folder or the same folder as the spectrum file that is to be analyzed.
Full Multi-path Bateman add-on (never expires) - $695
For non-equilibrium decay chains, VRF provides a special add-on package which uses full multi-path Bateman calculations to produce emitter files with all the lines and relative intensities appropriate to any user-selected decay time of any user-selected parent nuclide. All daughter nuclides and all their branching from multiple decay modes are accounted for. This powerful tool also provides for parent-daughter chains in transient equilibrium. Graphs suitable for reports and publications are produced showing the time evolution of each of up to 12 nuclides in a decay chain in any user-selected color scheme. As a special feature, with a single click of a button, non-equilibrium decay-chain files can be automatically created for direct inclusion in analysis.

Simulator add-on (never expires) - $695
The Simulator add-on provides unique capabilities that are useful for testing, learning, numerical experimentation, and training:
- From a user-selected "parent" spectrum, any number of "daughter" spectra can be automatically generated. Spectra are randomly different as they would be if actually acquired one after another in the laboratory, and Poisson statistics are strictly and accurately preserved. Sampling can be done either by sampling from the data, by sampling from the overall fit, or by sampling from the fit plus a hypothetical nuclide not present in the original spectrum. This last method makes possible training of analysts and testing of software for hard-to-obtain materials such as isotopes of plutonium and uranium. Acquisition time for daughter spectra can be set either as real time or live time, and initial random number seeds can be specified if reproducibility is required.
- The live acquisition of a spectrum can be simulated as it would be seen during the acquisition of an actual spectrum. Real-time presets and screen update intervals can be set by the user. This feature is useful for educational and training purposes when the use of a real acquisition system is not practical.
- Gaussian and Poisson probability distributions can be generated and graphically presented suitable for publication. The user can set the desired mean and (in the case of Gaussian statistics) the standard deviation, the limits of display, and the limits of integration of the distributions. This feature provides a quick and accurate method to calculate Poisson or Gaussian probabilities without the need for reference and interpolation in published tables.

XyPlot add-on (never expires)- $395
The XyPlot add-on makes creation of publication-quality graphics easy, simple, fast, and flexible. All graphs and plots in VRF are compatible with the XyPlot feature. XyPlot also works for any simple text list of XY pairs that a user desires to create of his or her own. Graphic title, axis titles, legends, colors, and up to six plots from XY text lists are easy to add and modify with any font size, type, and style. XyPlot is an indispensible tool for those who need to rapidly and easily create graphical plots for quality professional publications of all kinds.
New! Quality Control add-on (never expires) - $595
The Quality Control add-on for VRF complies fully with ASTM Standard D7282−14, "Standard Practice for Set-up, Calibration, and Quality Control of Instruments Used for Radioactivity Measurements". Easily track and document changes in energy, resolution, and efficiency for an unlimited number of detectors, and for any number of peak energies. Quality Control compliant with the ASTM specification can help with certification and the ISO process.

"Reference Spectrum" Efficiency File Service - $295
Creating a "Reference Spectrum" file for importing starting parameters for analysis with a new detector or geometry is described in detail in the Help topics but it can be an involved process. As a special service, we will do it for you. You only need to send us a spectrum file and a PDF scan or photo of the Certified Standard Reference Source that you used. We will send you a "Reference Spectrum" to put in your "ReferenceSpectrum" folder, usually in less than five days.
VRF 2024 New-User Full Analyst License - $1995

Introductory VRF 2024 - $395
This is the same as the complimentary limited-time Introductory license for workshop participation except that it is enables analysis for a full 12 months. Full credit for your purchase of an Introductory License will be applied toward a later upgrade to a Full Analyst License. This license enables analysis only of spectra for which a key file has been provided. Key files are already provided for all example spectra. The Introductory License is suggested for students of an instructor with a Full Analyst License as a low-cost way for students to analyze spectra that the instructor provides to them.
Note: A key file has the same name as the file to be analyzed, but has a file extension of "+KE". The key file must be placed in the KeyFiles folder or the same folder as the spectrum file that is to be analyzed.
