Investigation of the effect of cerium dioxide nanoparticles on the radiosensitivity of various cell types

Amorphous and crystalline cerium(iv) phosphates: biocompatible ROS-scavenging sunscreens

“…84 Ulitko et al showed that mesoporous CeO 2 nanopowder affects the sensitivity of different cells to radiation in different ways: it is able to protect human fibroblasts and increase radiation damage to macrophages and cervical carcinoma cells. 85…”

“…84 Ulitko et al showed that mesoporous CeO 2 nanopowder affects the sensitivity of different cells to radiation in different ways: it is able to protect human fibroblasts and increase radiation damage to macrophages and cervical carcinoma cells. 85 The viability of the NCTC L929 line mouse fibroblasts cell culture was further studied using differential staining (see Fig. 6).…”

Study of Radiation Resistance of WO3 Microparticles under Irradiation with Heavy Kr15+ and Xe22+ Ions

“…In fact, under irradiation with heavy ions, the main role in the deformation processes and consequences associated with radiation damage is played by the effects associated with the formation of vacancies and interstices, as well as their accumulation and agglomeration with an increase in the fluence or ion energy. At the same time, at low irradiation fluences, most of the resulting radiation defects annihilate, which does not lead to significant structural changes, as evidenced by a number of works [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. In the case of irradiation fluences above 10 12 ion/cm 2 , a stage of radiation damage accumulation is observed due to the effect of overlapping areas of radiation damage occurring along the trajectory of ions in the material, which leads to the formation of cluster defects that can significantly affect the change in the structural and strength properties of the irradiated material.…”

“…As is known, an increase in the degree of nuclear fuel burnup will be accompanied by an increase in the degree of radiation damage and, consequently, their accumulation in inert matrices [ 10 , 11 , 12 ]. At the same time, long-term irradiation of inert matrices with fission fragments or a neutron flux can lead to the appearance of metastable or nonequilibrium states in the structure, the destabilization of which can lead to the initialization of embrittlement processes or the formation of microcracks in the damaged layer.…”
