  The paper considers the problem of the extremely low frequency magnetic field
radiation generated by the tablet computers. Accordingly, the measurement of
the magnetic field radiation from a set of tablets is carried out. Furthermore,
the measurement results are analyzed and clustered according to the K-Medians
algorithm to obtain different magnetic field ranges. The obtained cluster
ranges are evaluated according to the reference level proposed by the TCO
standard in order to define dangerous areas in the neighborhood of tablet,
which are established during the typical work with tablet computers. Analysis
shows that dangerous areas correspond to specific inner components of tablet,
and gives suggestions to users for a safe usage of tablet and to companies
producing tablet components for limiting the risk of magnetic field exposure.
