The phosphogypsum is produced as a by-product of the manufacturing phosphoric acid or phosphate fertilizer from the phosphate rock on the wet process. In general, it contains relatively high concentrations of uranium series radionuclides such as 226Ra. This study surveyed overall radioactivity of the naturally occurring radionuclides in a facility using phosphate rock and evaluated the impact on the vicinity environment by the phosphogypsum.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.
An OpenURL link contains article metadata and directs it to the
OpenURL server of your choice. The OpenURL server can provide access
to the resource and also offer complementary services (specific

generated by different means.
If your librarian has set up your subscription with an
OpenURL resolver, OpenURL links appear automatically on the abstract pages.
