Supplementary investigation of two harbour sludge polders on which dwellings have been built

Aanvullend radiumonderzoek op twee met woningen bebouwde havenspeciepolders

Synopsis

This report contains the results of an investigation of radium contents of the soil at the locations Steendijkpolder-zuid, Maassluis (STPZ) and Woudhoek-noord, Schiedam (WH). The aim of this investigation is to determine whether the variation of the radium content within a harbour sludge polder with no topsoil (STPZ) is sufficient to enable quantification of the relation between the radium content of the soil and the radon concentration in dwellings. The second goal is to determine whether it is possible to determine the reduction factor of a topsoil (WH) for radon infiltration. The results show that in the STPZ the variation of the radium content within the polder is large enough to justify the expectation that corresponding variations in radon concentrations will be found. In WH the assess the effect of the topsoil, WH should be compared to another location.
