Norway increased the limit for caesium in reindeer meat for consumption to 6000 Bq/kg. This is extremely high. Sweden also increased their limit to 1500Bq/kg from 300Bq/kg in May 1987. Most countries have a limit of 600 Bq/kg. And even this figure is heavily criticised. But due to this limit much of the reindeer meat can be sold in Scandinavian countries
