Readings of tritium in seawater taken from the bay near the crippled Fukushima nuclear plant has shown 4700 becquerels per liter, a TEPCO report stated, according to Nikkei newspaper. It marks the highest tritium level in the measurement history.
Tokyo Electric Power Company (TEPCO) has detected the highest radiation level in seawater collected in the harbor of the crippled nuclear plant in the past 15 days, Nikkei reports
TEPCO said the highest radiation level was detected near reactor 1. Previous measurements showed tritium levels at 3800 becquerels per liter near reactor 1, and 2600 becquerels per liter near reactor 2. The concentration of tritium in the harbor’s seawater has been continuously rising since May, according to Nikkei. Also on Monday, a leak of highly contaminated water was discovered from a drain valve of a tank dike located on the premises of the nuclear plant, according to Fukushima’s operator responsible for the clean-up. 



Tritium is a radioactive isotope of hydrogen which is produced by nuclear reactors. It is potentially dangerous if inhaled or ingested. The legal limits for Tritium in terms of becquerels per liter vary from country to country. The World Health Organization has a limit of 10,000 Bq/l, but the European Union’s limit is much lower, at 100 Bq/l.
