I will try and keep this short and simple.

Tepco, the utility company that is managing the destroyed Fukushima nuclear power plant in Japan said that there were mistakes in the radiation levels they recorded last year. According to Japanese media, Tepco announced last week that what was recorded as 900,000 becquerels per liter of deadly beta radiation from a test-well last July was wrong and the actual level should read 5 million becq per liter. That's five times more than what they announced previously, and nearly 170,000 times more than the permissible level.
Tokyo Electric Power Co. said on 7 February that it will review a "massive" amount of radiation data it has collected at the crippled Fukushima Daiichi nuclear power plant because readings may be lower than actual figures due to improper measurement.
Tepco has not yet revealed results of 140 samples taken between June and November last year, fearing similar under-estimates. The company said that "malfunctions of analytical equipment" caused these errors, Asahi Shimbun said.

The operator of the damaged Fukushima Daiichi nuclear plant has decided to review radiation data after finding the initial readings may be much lower than actual figures.
Tokyo Electric Power Company, or TEPCO, says it has detected a record high 5 million becquerels per liter of radioactive strontium in groundwater collected last July from one of the wells close to the ocean.
Now this is really part of an ongoing pattern, dramatically under-report,
then get caught, then admit something and look into it, then say "Well,
there was more but, we haven't see anything in terms of human health,
so no harm no foul".
