In the wake of Japan's nuclear scare, Taiwan has adopted a series of protective measures against potential radioactive contamination, including screening mechanisms at the airports, as well as special inspections on food products imported from Japan. And some experts on food safety has advised the authorities to pay extra attention to seafood that came from the affected marine areas.

The radiation alert sounds whenever imports contain excessive amounts of radioactive contamination.

Even though the products are packed away in the cargo containers, inspectors can easily detect any traces of radiation.

Customs officials will even arrive on the market to see which items contain radioactive substances.

Kaohsiung's port is Taiwan's biggest port for receiving cargos of imports.

It is also where Taiwan's only anti-terror radiation detector is located.

The 38-portal detector and its other handheld devices are being used to keep close guard from contaminated products and document the radioactivity in the environment.

Port customs will also send inspectors to the market to check on imported food products from Japan.

However, food sanitation experts say that while processed foods that are contaminated with radiation can pose a risk to public health, it would take a whole month to reach Taiwan.

Instead, fresh fish imported from Japan's coasts are more likely to be contaminated and will be strictly monitored.

Food sanitation experts are urging the government to quickly conduct spot checks as a pre-emptive measure but are also reminding the public not to worry and to eat different foods to avoid ingesting too much radioactive substances.
