From Fukushima Diary
On 2/10/2016, NRA (Nuclear Regulation Authority) announced they are going to abandon 2,500 of 3,600 radiation monitoring posts in Fukushima prefecture from April of 2017.
NRA states this is due to the limited resource such as budget and equipment.
2,500 posts to be removed are situated in public facility including schools.
NRA comments no significant change has been detected recently. However, the monitoring posts were also observed to become “under maintenance” occasionally.
