Contents of the package:     with VIDEO

Nuclide data : types of radiation (α, β, γ, n, ), spectra, attenuation coefficients, irradiation data, dose coefficients, transport conditions, shielding etc. Bookkeeping of nuclides used in hospitals etc.

Radiological badges of employees; overall bookkeeping system with statistical applications (individuals over years and groups, locations over individuals and years). Automated input from badge measurement files, and automated check with local personal data files, using matching algorithms (e.g. Johnson vs. Jonson). Extensive output in table form and graphic figures. The program is a full administrative system, providing data needed for Institutional Reports and Nuclear Law Dossiers (NL: KEW-dossiers). It runs on your local computer, without online connections, so less danger for hacking or data theft.

Laser damage in eye and on skin. Pulsed and continuous lasers. Calculation of Nominal Ocular Hazard Distance, according to EU-Directive 2006/25/EU. New data are under development.

The package was originally developed by the author (see main page) for use in his Institute. It is now made available for free to the  (former) colleagues. The underlying data used are taken from open sources or are made available on a personal basis.
