In the event of a nuclear accident during which radioactive substances are released into the environment, the authorities will inform the population of any preventative bans on food consumption via the website www.infocrise.lu, their Twitter account and the national media.
One of the main considerations in the event of a nuclear accident is protecting the food chain and feed for livestock. When radioactive substances are deposited on the ground, plants or water they risk contaminating the food chain.
The surface of fruit and vegetables and feed for animals can be contaminated by the deposition of radioactive material contained in the air or rainwater. In such circumstances, the leafy part of plants can effectively intercept airborne radioactive contaminants which make them susceptible to becoming contaminated.
If dairy cows graze on grass contaminated by the first fallout, radionuclides will quickly end up in their milk. In general, fresh food like milk, leafy vegetables and fruit can be contaminated by a nuclear accident.
Soil can also be contaminated as radionuclides with long life spans like caesium 137 and strontium 90 can accumulate in the ground which then becomes a source of secondary environmental contamination.
The various food restrictions will, if applicable, be communicated to the population via the media and the website www.infocrise.lu.
