Computational tools for radiation science

Specialist radiation calculations, in the browser.

Radiation Lab builds calculation and simulation tools for radiation science and engineering. Each one runs in your browser, states the standard or model it implements, and gives you a record you can keep.

Open RadiMeter → See the fields

Four schematic panels on one dark board: a measured response curve with error bars, a geological column with a migration path through the strata, a beam attenuating through a stack of shielding slabs, and nested dispersion contours spreading from a release point.

Fields

Four areas of radiation science and engineering. One tool is published; the rest are in development, and this page names a tool only once it exists.

A response curve plotted across a grid with measurement points and an amber reference line, beside a handheld survey meter and probe.

Instrument metrology

Available

Characteristic evaluation of radiation detection instruments against IEC standards — energy and angular response, linearity, statistical fluctuation, response time, alarm accuracy and the rest of the test set.

Open RadiMeter →

Cross-section of deep geological disposal: layered rock strata, an emplaced waste canister, and a plume front drawn as nested concentration contours with an amber boundary.

Waste disposal and radionuclide transport

Available

Migration of radionuclides through the geosphere after deep geological disposal. Thermodynamic speciation and surface-complexation modelling coupled to transport, so that sorption and solubility are derived rather than assumed.

The interface is in Korean for now. Open M-Phreefiteq →

A source emitting rays that thin as they pass through a stack of shielding slabs, with an exponential attenuation curve below and an amber limit line.

Dose and shielding

In development

Dose assessment and shielding design — attenuation through layered materials, build-up, and the conversion between measured quantities and the protection quantities a limit is written in.

Nested dispersion contours fanning downwind from a release point across a topographic outline, with a wind rose and an amber threshold isopleth.

Environmental radioactivity and dispersion

In development

Atmospheric and aquatic dispersion of released radionuclides, and the treatment of environmental monitoring data — concentration fields, deposition, and the exposure pathways that follow from them.

How the tools are built

Stated basis

Every calculation names the standard, clause or model it implements. Where a published standard defines the method, the clause is cited and the text is not reproduced.

Nothing to install

The tools run in the browser. Codes of this kind normally mean a desktop install and an input deck; here the input is a form and the result is immediate.

A record you keep

Results export to a spreadsheet or print as a report. Your input data stays in your browser unless you choose to send it.

Scope and limitations

Radiation Lab is not an accredited calibration or testing laboratory, and the tools published here do not replace accredited calibration, testing, or a licensed safety assessment. A result is only as good as the data and assumptions entered into it, and remains the responsibility of the person who records it. Each tool states this in full, and the disclaimer gives the complete text.
