 Neither the Jewish religious leaders in Poland nor the authorities allowed archaeological excavations at the camp out of respect for the dead. Approval for a limited archaeological study was issued for the first time in 2010 to a British team from Staffordshire University using non-invasive technology and Lidar remote sensing. The soil resistance was analysed at the site with ground-penetrating radar. Features that appeared to be structural were found, two of which were thought to be the remains of the gas chambers, and the study was allowed to continue.
