A spatial analysis of data on radioactive pollution on land at Thule, North-West Greenland is presented. The data comprises levels of ²⁴¹Am and ^239,240Pu on land. Maximum observed level of ²⁴¹Am is 2.8×10⁵ Bq m^-2. Highest levels were observed near Narsaarsuk. This area was also sampled most intensively. In Grønnedal the maximum observed level of ²⁴¹Am is 1.9×10⁴ Bq m^-2. Prediction of the overall amount of ²⁴¹Am and ^239,240Pu is based on grid points within the range from the nearest measurement location. The overall amount is therefore highly dependent on the model. Under the optimal spatial model for Narsaarsuk, within the area of prediction, the predicted total amount of ²⁴¹Am is 45 GBq and the predicted total amount of ^239,240Pu is 270 GBq.
