Abstract Although radio frequency (RF) electromagnetic fields emitted by mobile phones have received much attention, relatively little is known about the extremely low (ELF) magnetic phones. This paper summarises ELF flux density measurements on global system for communications (GSM) phones, conducted as part of MOBI‐KIDS epidemiological study. The main challenge to identify a small number generic phone models that can be used classify exposure different reported in Two‐dimensional were performed 47 GSM at distance 25 mm. Maximum resultant values 217 Hz had geometric mean 221 (+198/−104) nT. Taking into account harmonic data, suggest could make substantial contribution general population. maximum and easily available variables poorly correlated. However, three groups defined basis field pattern indicating manufacturers shapes may important parameters linked spatial characteristics field, categorization study achievable representative Such would result twofold gradient between high based type used, although there was overlap grouping.
