What are some of the things that happened when the radiation leaked in Japan?

Question:

Answer:

On August 29 at 6 p.m., the Nuclear Industrial Safety Agency (NISA) announced
at a press conference that TEPCO had falsified
voluntary inspection reports and concealed it
for many years. TEPCO admitted the stated
facts at the press conference later in the same
day. According to the agency, TEPCO has
falsified the inspection records and attempted
to hide cracks in reactor vessel shrouds in 13
units of the 17 nuclear power plants owned by
TEPCO, including Fukushima I (6 reactors),
Fukushima II (4 reactors), and Kashiwazaki-
Kariwa (7 reactors). However, the agency
maintained that there should be no problem
regarding the safety of the nuclear power
plants. Ironically, the safety assessment by the
agency was based on TEPCO’s calculation.
