PNRI radiation data for the Philippines as of March 29, 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 nanosieverts 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.

Wind forecasts for Friday are unfavorable for the Philippines
