heal.abstract	The attenuation of the radio signal in the near field of a tetra handheld device due to the presence of human body is measured. By including a confidence margin for the mean and the standard deviation of the measurements we find in open area 8.4dB attenuation when the handheld device is at talking position close to the head and 19.3dB when it is placed at the belt. In urban environment the corresponding values are 11.2 and 9.2dB respectively. Detailed measurements are presented and discussed.	en
