Impact of shortened crop rotation of oilseed rape on soil and rhizosphere microbial diversity in relation to yield decline [PDF]
, 2013 Oilseed rape (OSR) grown in monoculture shows a decline in yield relative to virgin OSR of up to 25%, but the mechanisms responsible are unknown. A long term field experiment of OSR grown in a range of rotations with wheat was used to determine whether ...

The variance-covariance method: Microdosimetry in time-varying low dose-rate radiation fields [PDF]
, 1988 The variance-covariance method is employed at low doses and in radiation fields of low dose rates from an241Am (4 nGy/s) and a90Sr (300 nGy/s) source. The preliminary applications and results illustrate some of the potential of the method, and show that ...

Neutron and photon out-of-field doses at cardiac implantable electronic device (CIED) depths
Applied Radiation and Isotopes, 2021 The accuracy of an out-of-field dose from an Elekta Synergy accelerator calculated using the X-ray Voxel Monte Carlo (XVMC) dose algorithm in the Monaco treatment planning system (TPS) for both low-energy (6 MV) and high-energy (15 MV) photons at cardiac implantable electronic device (CIED) depths was investigated through a comparison between MCNPX ...

Companding technique for high dynamic range measurements using gafchromic films
, 2011 We propose a methodology to perform dose measurements using gafchromic films which can span several decades of dose levels. The technique is based on a rescaling approach using different films irradiated at different dose levels.

Out‐of‐field doses and neutron dose equivalents for electron beams from modern Varian and Elekta linear accelerators [PDF]
Journal of Applied Clinical Medical Physics, 2016 Out‐of‐field doses from radiotherapy can cause harmful side effects or eventually lead to secondary cancers. Scattered doses outside the applicator field, neutron source strength values, and neutron dose equivalents have not been broadly investigated for high‐energy electron beams.
