Notes: There is no national radon action plan. However a working group ‘Radon evaluation and radon action plan’ was set up in 2015 by RSC and radon measurements and situation assessment was done in Latvia. This is a weblink to the homepage of RSC with information on this process (in Latvian):
<<http://www.vvd.gov.lv/kontrole/radona-gazes-kontrole/>>. There are no national radon regulations for buildings with high public occupancy as action level and limit value is set for all buildings (Part 8 of Cabinet Regulation No. 149). Cabinet Regulation No.149 action levels and limit values are set:
Action level: If construction materials and construction products contain 226Ra the specific radioactivity of which exceeds 100 Bq/kg, the performer of construction work shall ensure appropriate protection measures to prevent the limits.
