General Description
The Tracerco T401 is a portable battery operated radiation contamination monitor, capable of
measuring alpha, beta and gamma radiation over a wide range of energies. Radiation detection is
carried out using a thin window Geiger Muller Tube located in a detachable probe adjacent to the head of
the monitor.
Tracerco has extensive experience of the practical difficulties which may be encountered when
attempting to carry out contamination monitoring of both man -made and naturally occurring
radioactivity under hostile and restrictive environmental conditions, particularly those which relate to
the Chemical, Mining, Nuclear and Oil and Gas Industries.
The Tracerco T401 has been designed to address many of these practical issues in providing a
monitor which is reliable, versatile, easy to use and capable of operating in adverse environmental
conditions.
A key feature of the Tracerco T401 is the capability to allow pre-programming of detection efficiency
data for a wide range of radionuclides enabling recorded counts/sec to be automatically translated
into more radiologically significant units of Bq/cm

. There are additional design elements which are
fully described in this manual and combine to make the T401 an invaluable instrument for use in
radiation contamination monitoring.
