Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

open access: yesThe Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Raw Material Economisation in Aotearoa New Zealand: Evidence for Manufacture and Recycling of Adzes on Ahuahu Great Mercury Island

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Raw materials are used to characterise the early settlement of Aotearoa Te Wai Pounamu New Zealand by Māori. Current models suggest change in raw material use over time occurred in response to changing social organisation and reduced resource availability. However, few studies have examined spatial variation in raw material use.
