The present article contains information about the activities and origin of 137Cs, 238Pu and 239+240Pu in the North-eastern Poland. Analyzed samples were collected in 59 locations where forest litter A0 and humus A1 were collected in 1991. An approximate map of the Chernobyl fallout component 239+240Pu was prepared on the basis of received results. The largest Chernobyl 239+240Pu contamination occurred in north-eastern and eastern part of the investigated area, reaching 22.1±1.6 Bq m-2.
