The circle sizes and colours on this map are chosen purely for visual clarity. They do not indicate any actual radiation risk. Ambient gamma dose rates across the UK are consistently well within safe limits. Variation between stations reflects natural background differences — geology, altitude, and weather — not hazard levels.
