Workshop  on environmental effects of chronic low level radioactive contamination

 

Panel

Aim

By bringing together scientists involved in environmental and/or laboratory studies of radiation effects, allied ecological fields and radiation protection specialists we hope to:

  • discuss field based studies of effects of radiation at low chronic dose rates
  • investigate the available radiation effects data for low dose rates and consider how these can be incorporated into improved radiation protection systems;
  • discuss current methods for deriving numerical dose rate benchmarks for application in environmental assessments;
  • consider uncertainties in dose estimation including measurements in the field
  • start to understand the basis behind some of the contrasting results and interpretations on the effects of radiation in the environment;
  • agree future research priorities and mechanisms whereby data can be shared.
  • gain a greater understanding of the impacts of radiation on wildlife
