In continuity to the studies of the UFPA in cemeteries, a site for controlled
tests was implanted in the cemetery of the Tapanã in 2007. Three targets were
buried under a profile: a human body, a tunnel and a box with material simulating
military weapons. The objective was to investigate the answers of the geophysical
methods electrorresistivity, spontaneous potential and radiometry to the body
decomposition throughout the time in order to subsidize ambient inquiries on the
signature of the plume of contamination of the necroleachate. Moreover, being the
three also material targets of police inquiries, we searched the applicability of those
methods in forensic geophysics. The results gotten with electrorresistivity allowed to
identify the ground dug. The results with spontaneous potential showed an increase
in voltage on the corpse. Radiometry showed that the corpse and the tunnel
increased the background. The results shown here evidence that the used methods
have potential for environmental studies in cemeteries and forensic investigation in
the following order: electrorresistivity, spontaneous potential and radiometry. |
