Japan's nuclear watchdog has deleted the results of thyroid check-ups for at least 1000 Fukushima children exposed to radiation, following the devastating earthquake and tsunami in March.
Critics have accused it of denying the public accurate information about the crisis, the ABC reports.
Japan's Nuclear Safety Commission had earlier uploaded the test results of the children who were checked to see if radioactive substances were accumulating in their thyroid.
It has been revealed that earlier in August, the commission removed the data from its website, citing privacy reasons.
Health specialists have condemned the decision, saying the commission fears a negative public reaction to children's exposure to radiation from the crippled Fukushima Daiichi plant.
