Municipalities where the radioactive facilities are located and the number of sources according to their category.

Location of alarms to warn the population if there is a chemical risk in the case of an accident in premises nearby.

Thematic coverage of the municipalities of Catalonia in which the obligation or recommendation of the municipality to draw up the Municipal Action Plan (PAM) for chemical risk in the transport of dangerous goods by road and rail is represented, as well as the current status of the plan

Municipalities that within their territorial scope have facilities attached to the radiological surveillance protocol.

Municipalities within a distance of 1 km around each radiological surveillance facility (IVR). Therefore, municipalities are obliged to draw up a municipal action plan for radiological risk.

Locations where the radioactive facilities are located and the number of sources according to their category.

Delimitation of the security band with control of compatible vulnerable elements (no residential use and public concurrence, except for compatible industrial uses) based on the zone of limit effects or extremes outside, that is, this area includes the area where the consequences about the population or vulnerable elements are especially significant due to the special intensity of the effects of the emergency.

Municipalities within a distance of 2 km around each radiological surveillance (IVR) facility. Therefore, it is municipalities that are recommended to draft a municipal action plan for radiological risk.

This represents the alert coverage of sirens installed on dams. Some approximations have been made by generating buffers with a predefined coverage radius based on the technical specifications of the sirens, while others have employed acoustic propagation models that incorporate factors such as attenuation, sound dispersion, and the influence of topography.

Polygons which define the range of sound corresponding to the alarms. In accordance with each type of alarm, the sound radius covered can be 800 or 400 metres away from the siren, or maybe unidirectional, covering a distance of 700 m with a 70º opening.
