Nuclide Navigation-Pro, interactive nuclide map, reference software

nuclide map

The main interface of NuclideNavigator-Pro is a nuclide chart, which can be displayed in a variety of information views, including General Electric, Karlsruhe and trilinear formats. The General Electric and Karlsruhe formats use a common layout with a nuclide grid defined by the number of protons on the vertical axis and the number of neutrons on the horizontal axis, so that isotopes of common elements are displayed in rows. However, they use different color schemes, with the GE view representing nuclide half-lives and neutron cross sections, and the Karlsruhe view representing nuclide decay modes. The trilinear format, found in both color schemes, arranges isotopes on the diagonal. When "moving down" the decay chain, the layout uses vertical navigation for beta decay and horizontal movement for alpha decay, rather than the diagonal movement associated with traditional grid layouts. The diagram can also be limited to the natural series (thorium, neptunium, uranium, actinium) to simplify the evaluation of these decay chains.

Intuitive query tools make it easy to find the sources of gamma and alpha rays. Not only does it set an energy range for potential nuclide matches, it can also be filtered by nuclide production mode, half-life, and secondary emission. This additional information can greatly improve the quality of search results, helping spectroscopy experts evaluate analysis results and optimize libraries.

Nuclide and elemental emission data

Nuclide properties can be accessed by double-clicking on the nuclide in the nuclide chart or on the peak energy in the peak search results. The property page includes basic nuclide information, such as half-life, energy emission in the ground state and metastable state, parent nuclide and daughter nuclide, and their generation probability. Clicking on the parent nuclide and daughter nuclide will navigate up or down the decay chain(If applicable)。

Energy emission types can be found inγ、βandαSwitch between emissions and sort by energy or branch ratio. Based on a specific detector typeIncludes energy range, peak width and relative efficiencyMatched gamma spectra are also available for synthetic spectra of related radiation types. These synthetic spectra give spectrometers a good idea of ​​the different types of instrumentation and can be used as a teaching aid in place of actual measurement data. Synthetic spectra and their raw spectra can be saved in ORTEC standard spectral format for analysis in GammaVision and can also be used in other software applications, including spreadsheets and presentations.

You can use the library lister to generate comprehensive reports of nuclide and emissions data for a subset of nuclides from the master library. The content of the report is controlled through selectable parameter options, including decay mode, energy range, parent/daughter nuclides and several other useful parameters.

Element properties can be accessed by double-clicking on the element box in the nuclide diagram. The property page includes basic element abundance information and different electron shells.xRay energy/intensity. When evaluating different materials in relation to detector shields, attenuation layers, and sample matricesxWhen the ray is emitted, this information is extremely valuable.

Library manager
The Library Manager greatly simplifies the generation of application-specific libraries. Simply load a master library and drag the desired nuclides to the target library list. Items can also be set to limit which nuclides and peaks are copied to the target, and content can be manually adjusted based on the intended library use. Target libraries can be saved as standardORTEClibrary format for use inGammaVisionapplication, or saved in an Extensible Markup Language format that can be read in any text editor, or can be processed by a custom application if desired.

Decay Calculator
Nuclide Navigator-Professional NuclideNavigator-Pro's decay calculator makes complex decay calculations easy to perform and visualize. It includes the simple decay or growth of a single nuclide, the parent-neutron decay, full decay chain, user-defined nuclide groups and neutron counting ratesCf-252calculation. Results for each nuclide and total activity are displayed graphically in addition to being provided in a comprehensive report. Similar values to those for single nuclides can also be obtained when evaluating complete decay chainsGamma ray synthetic spectrum. This energy spectrum view is useful for a relatively simple parent-Sub-relations and complex natural decay chains containing large numbers of nuclides are very useful.

Periodic Table of Elements and Unit Converter

The periodic table is a rich interactive resource of the properties of elements. The main interface is a classic periodic table of the elements, color-coded with information related to chemical groups and the element's physical form at room temperature. Basic physical properties are displayed when the mouse is moved over an element, and more detailed chemical properties are accessed by double-clicking on an element. Right-click on an element to get a brief history of each element.

Unit Converter is a utility for converting common units of measurement. Simply enter a value in a known unit and the value in the desired unit is instantly calculated.

Measurement types include: Acceleration, angle, area, concentration, data storage, density, energy, flow, force, length, light, mass, power, pressure, radiation-activity, radiation-exposure, radiation-absorbed dose, radiation-dose equivalent, temperature, time, torque, speed and volume. Most common units of every measurement can be converted, as well as quite a few less common units!
