摘要：

The reactions of gamma-irradiation on a rod type FeOOH in the presence of isopropanol and water have been investigated. With the continued gamma-irradiation, a rod type FeOOH nanoparticle disappeared and the product was a spherical gamma-Fe2O3 nanoparticle, which had an average size of 30 nn. XRD, SAD and TEM were used to characterize the structural characterization and to determine their morphology, respectively. The VSM spectrum was obtained to study magnetic properties of the products.
