Fukushima-Daiichi Nuclear Power Plant Accident in Japan

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.
