Reactor No. 2 released 360 quadrillion becquerels of radioactive materials, about 40 percent of radioactive material inside the reactor. The No. 1 reactor released 130 quadrillion becquerels of radioactive materials and No. 3 released 320 quadrillion becquerels.
24
Tepco said it is unsure of the source of 110 quadrillion becquerels of radioactive materials, but it does not believe the No. 4 reactor building emitted radiation.
