This document discloses a solution for controlling radio emissions in cells of a cellular communication system. According to an aspect, a method includes determining a set of cells having a spatially overlapping coverage area in a sector, wherein the set of cells includes at least a first cell and a second cell; determining a maximum total radiation level for the sector; determining a priority of each cell in the set of cells such that the first cell is prioritized over the second cell; and allocating, on the basis of the maximum total radiation level and said priorities, to each cell in the set of cells a parameter indicating a maximum radiation level in the respective cell, wherein said allocating is performed such that a smaller power reduction from a maximum transmission power is allowed for the first cell than for the second cell.
