The dangers of Japan’s radioactive water

Japanese authorities warned that radioactive contamination levels in tap water in Tokyo can be dangerous for infants under one year.

Radioactive gases which have escaped the Fukushima nuclear plant contaminated supplies, and now the radioactivity in water in the Japanese capital has exceeded the allowable limits for children.

According to Tokyo Governor Shintaro Ishihara, the levels of radioactive iodine in tap water in the city is twice the recommended dose for children and babies.

United States, meanwhile, announced it will stop imports of milk and fresh products from the affected areas in Japan and South Korea said it is considering “actively” a ban on food imports from that country.

What are the allowable limits of radioactivity in the water?

Japanese authorities reported that levels of radioactive iodine 131 in the tap water in Tokyo rose to 210 becquerels (Bq) per kilogram.

The limits recommended as safe by international health authorities are 300 Bq and 100 Bq for adults to babies and toddlers.

While some Japanese officials suggest that this water only becomes a health risk if consumed over a long period of time, Tokyo is recommended that children under one year do not drink, nor be used for mixing of formula.

As the BBC says Professor Tim Lang, an expert on Food Safety, University of London, United Kingdom, “the security levels are set at low. That is, within them and to include a factor security that takes into account the consumption of long-term product. ”

“Even so, the fact that these levels have already exceeded the recommendations in the water of Tokyo and around the plant, is extremely worrying,” he adds.

“In Tokyo it comes to almost double the recommended level of radioactive iodine, and near the plant have exceeded levels seven times the recommended amount.”
