Taiwan will conduct radiation checks on some types of container cargo arriving from Japan, the island's legislature said on Wednesday.

The body's Finance Committee ruled that waste materials such as plastic, scrap metal and paper must be checked with radiation meters upon arrival at the island's four seaports: Keelung, Taipei, Taichung and Kaohsiung.

Jao Ping, director general of the Customs Administration agency, told reporters the measure will go into effect as early as this week.
