TLDR
In this paper, the effects of self-radiation damage from alpha decay in Gd2Ti2O7 were investigated by studying specimens doped with 244Cm and found that the radiation-induced microstructure consists of individual amorphous tracks from both the alpha-recoil particles and the spontaneous fission fragments.About:

Nuclear waste disposal—pyrochlore (A2B2O7): Nuclear waste form for the immobilization of plutonium and “minor” actinides
TL;DR: In the last decade, there has been substantial interest in the use of the isometric pyrochlore structure-type, A2B2O7, for the immobilization of actinides.

Radiation effects in nuclear waste forms for high-level radioactive waste
TL;DR: In this paper, a comprehensive review of radiation effects due to γ-, β- and α-decay events, as well as from actinide doping experiments and particle irradiations, on nuclear waste form glasses and crystalline ceramics was provided.

Radiation stability of gadolinium zirconate: A waste form for plutonium disposition
TL;DR: In this article, Zirconate and titanate pyrochlores were subjected to 1 MeV of Kr+ irradiation and showed a systematic change in the susceptibility to radiation-induced amorphization with increasing Zr content.

Radiation-induced amorphization of rare-earth titanate pyrochlores
TL;DR: In this paper, the microstructure evolution of pyrochlore compounds was characterized using in situ transmission electron microscopy (TEM) and the critical amorphization temperature, T T c, was found to increase with increasing A-site cation size.

Immobilisation of high level nuclear reactor wastes in SYNROC
TL;DR: In this article, the elements occurring in high-level nuclear reactor wastes can be safely immobilised by incorporating them within the crystal lattices of the constituent minerals of a synthetic rock (SYNROC).

Structural characteristics of pyrochlore formation
TL;DR: By calculating the value of unknown oxygen positional parameter x for a large number of A3+2B4+2O7 pyrochlores, it was determined that increasing the radius of the A cation in a series of constant B increased the value x as discussed by the authors.

Pyrochlores. V. Thermoanalytic, X-ray, neutron, infrared, and dielectric studies of A2Ti2O7 titanates
TL;DR: In this article, a number of compositions A23+Ti24+O7 and related mixed phases were investigated for the trivalent lanthanons from Sm to Lu, and for Y, the homogeneous A2Ti2O7 phases were of the cu...

Measurement of the fracture properties of brittle solids by hertzian indentation
TL;DR: In this article, the authors made an analysis of the relationship between load and crack extension in the Hertzian indentation of a solid surface with a spherical indentor and proposed that the minimum load for ring-crack formation becomes independent of the flaws in the solid if these have a size above a certain threshold value.
