Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

METHODS OF ASSESSMENT OF THE RELATIVE BIOLOGICAL EFFECTIVENESS OF NEUTRONS IN NEUTRON THERAPY

open access: yesСибирский онкологический журнал, 2017
The relative biological effectiveness (RBE) of fast neutrons is an important factor influencing the quality of neutron therapy therefore, the assessment of RBE is of great importance.

Clinical consequences of relative biological effectiveness variations in proton radiotherapy of the prostate, brain and liver [PDF]

open access: yes, 2013
Proton relative biological effectiveness (RBE) is known to depend on the (alpha/beta)(x) of irradiated tissues, with evidence of similar to 60% variation over (alpha/beta)(x) values from 1-10 Gy.
