ARTM View™

Atmospheric Radionuclide Transport Model

Technical Specifications

ARTM View is an interface for the ARTM model. See below the technical specifications for this model:

Parameter

Description

Model Name

ARTM - Atmospheric Radionuclide Transport Model

Developed By

German Federal Office for Radiation (BfS)

Model Type

Lagrangian particle tracking air dispersion model for radionuclides

Range

100 times the source height. For example, for a stack height of 250 m a range of up to 25 km in radius is realistic.

Source Types

Point, area, volume, line, cooling tower

Pollutants and Emissions

Multi-radionuclides can be model in a single run
Emissions can be specified as constant or time-dependent in Bq/s

Meteorology

Hourly meteorological data in AKTerm, and AKS formats are accepted by the model. The AKT, AKTerm format contain the hourly data for wind direction, wind speed, rain rate, and stability class according to Klug/Manier. The AKS file contains the statistics of wind direction, wind velocity, dispersion class, and rain rate.

Note: To support users without access to the above met file formats, ARTM View accepts a CSV file with the following hourly met data parameters: wind direction (deg), wind speed (m/s), Monin-Obukhov Length (m), and rain rate (mm).

Terrain

Flat or Elevated. The model accepts terrain data in GridASCII format.

Note: ARTM View accepts the following terrain data formats: GridASCII, XYZ, USGS DEM, and SRTM.

Receptors

Single or nested grid, monitor points

Other Options

Several additional model options are available, such as:

  • Wind field around buildings and terrain
  • Variable source parameters (temperature, thermal flow, discharge velocity, and time scale

Output Type

The output type depends on the pollutant being modeled. Examples of possible outputs are:

  • CNC: Annual mean of concentration in units of Bq/m³
  • DRY: Annual mean of dry deposition in units of Bq/(m²*s)
  • WET: Annual mean of wet deposition in units of Bq/(m²*s)
  • G01: Annual mean of gamma cloud radiation 0.1 MeV in units of Bq/m²
  • G10: Annual mean of gamma cloud radiation 1.0 MeV in units of Bq/m²
  • Estimative of the statistical uncertainty, and
  • Time series of hourly concentration in units of Bq/m³ (only at monitor point locations)

Regulatory Status

New standard for the dispersion and deposition calculation of airborne radioactive materials according to the German Nuclear Act.
