Nuclide diagram

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

Through intuitive query tools, it is easy to find the sources of gamma and alpha rays. It can not only set an energy range for potential nuclide matching, but also filter through nuclide production patterns, half lives, and secondary emissions. These additional information can greatly improve the quality of search results, help spectral experts evaluate analysis results, and optimize the library.

Nuclide and elemental emission data

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

The type of energy emission can beγTheBandalphaSwitch between launches and sort them by energy or branch ratio. Based on specific detector typesIncluding energy range, peak width, and relative efficiency, etcThe matched gamma spectrum can also be used for the synthesis spectrum of related radiation types. These synthesized spectra provide spectrographers with a good concept of different types of instruments, which can be used as teaching aids to replace actual measurement data. The synthesized energy spectrum and its original spectrum can be saved in ORTEC standard spectrum format for analysis in GammaVision, as well as for other software applications, including spreadsheets and presentations.

A library lister can be used to generate a comprehensive report of nuclide and emission data for a subset of nuclear elements from the main library. The content of the report is controlled through optional parameter options, including decay mode, energy range, and mother/Sub nuclide and several other useful parameters.

You can access element properties by double clicking the element box in the nuclide chart. The property page includes information on the abundance of basic elements and different electronic layersxRadiation energy/strength. When evaluating different materials related to the detector shielding layer, attenuation layer, and sample matrixxDuring radiation emission, this information is extremely valuable.

Spectrum Library Manager
The spectral library manager greatly simplifies the generation of application specific libraries. Just load a main library and drag the required nuclide to the target library list. Items can also be set to restrict which nuclides and peaks are copied to the target, and the content can be manually adjusted according to the expected library use. The target library can be saved as a standardOrtecLibrary format, in order toGammaVisionUsed in applications, or saved in an extensible markup language format that can be read in any text editor, or if needed, can be processed by custom applications.

Decay calculator
Nuclide navigator-The professional NuclideNavigator Pro decay calculator makes complex decay calculations easy to execute and visualize. It includes simple decay or growth of a single nuclide, parent-Sub decay, complete decay chain, user-defined nuclide groups, and those with neutron counting ratesCf-252The calculation. The results of each nuclide and total activity are not only provided in the comprehensive report, but also displayed graphically. When evaluating the complete decay chain, it is also possible to obtain similar results as a single nuclideGamma ray synthesis spectrum. This spectral view is suitable for relatively simple mother-Subrelationships and complex natural decay chains containing a large number of nuclides are very useful.

Periodic Table of Elements and Unit Converter

The periodic table is a rich interactive resource of element properties. The main interface is the classic periodic table of elements, with color coded information related to chemical groups and the physical form of elements at room temperature. When the mouse moves over an element, basic physical properties will be displayed, and double clicking on the element will access more detailed chemical properties. Right click on an element to get a brief history of each element.

Unit converter is a utility used to convert commonly used measurement units. Just enter the value of a known unit and immediately calculate the value of the required unit.

Measurement types includeAcceleration, angle, area, concentration, data storage, density, energy, flow rate, force, length, light, mass, power, pressure, radiation activity, radiation exposure, radiation absorbed dose, radiation dose equivalent, temperature, time, torque, speed, and volumeMost common units of measurement can be converted, and there are also quite a few less commonly used units!
