INFORMATION BULLETIN № 15 29 March 2011
Update as of 11:00 AM
The DOST-PNRI continues to closely monitor the situation at the Fukushima-Daiichi Nuclear Power Plant.
The condition in the plant remains very serious but not worsening.
The Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) air monitoring station in the Philippines being serviced by the DOST-PNRI detected the following radioactivities:
| Radioisotope | March 23 *(in μBq/m3) | March 24 (in μBq/m3) | March 25 (in μBq/m3) | March 26 (in μBq/m3) |
| Iodine-131 | 33 | 480 | 54 | 20 |
| Cesium-134 | 4.2 | 92 | 6.3 | 0.7 |
| Cesium-137 | 5.7 | 120 | 7.7 | 0.7 |
*microbecquerels per cubic meter
The peak values on March 24 correspond to a dose rate of 0.015 nanosievert per hour (nSv/hr) which is approximately 1/7000 of the dose rate due to natural radioactivity.
Latest DOST-PNRI RADIATION LEVEL CHECK at PNRI grounds as of 1:00 PM, March 29, 2011: 94 to 118 nSv/hr (nanosieverts per hour), STATUS: NORMAL
Based on the PAGASA model, air parcel coming from northern Japan is forecasted to move east towards the Pacific Ocean for the next three days.
