Radioactive contamination levels from Japan’s crippled Fukushima nuclear plant have fallen sharply since the accident but will be “chronic and lasting” for many years, a French watchdog said Tuesday.
[...] Didier Champion, crisis manager at the Institute for Radiological Protection and Nuclear Safety (IRSN) [said] “Today, and for many years to come, we will have a situation of chronic and lasting contamination of the environment.” [...]
“There are risks of chronic exposure at low dosage, and without care this can build up over time,” he warned.
[...] IRSN said [...] the impact on the civilian population over the long term, and on emergency workers and plant employees, remained unclear.
By the Numbers
- IRSN said the main radioactivity leaks occurred between March 12-25 in about 15 incidents, “of which the biggest probably took place before March 15″
- Provisional estimate that 408 peta-becquerels, or 408 million billion becquerels, of radioactive iodine had been emitted into the air
- 10 times lower than in the 1986 Chernobyl
- Caesium of all kinds released at Fukushima was estimated by the agency at 58 peta-becquerels
- Three times less than Chernobyl
- Caesium 137 accounted for 21 peta-becquerels
- Of around 24,000 square kilometers (9,200 square miles) of land contaminated by caesium 137
- only 600 sq. kms (230 sq. miles) breached a safety threshold of 600,000 becquerels per square metre
- However, there remained “hot spots” of contamination, up to 250 kilometres (156 miles) away
