Document Summary
Impacts of ionising radiation on non-human biota; issues and challenges. Radiation protection is developed by physicist concerned about the dose. Exposed to chemical pollution, air pollution and hydrocarbons/organics in the environment. Bioata exposed to chronic low doses of multiple stressors including radiation data are mainly for acute exposures. Whole areas in ecology where we know nothing about radiation effects. Think about what it critical and what makes the ecosystem function. Humans care about particular species more than others etc. Sponges in the marine environment (no idea what radiation does to them or their reproduction) A little dose of radiation, or other low level exposure is the least of the problems facing most non -humans (realistic view of radiation) Nothing that tells us radiation caused a particular harm. Limited studies of exposure to low dose of radiation. New mainly ethical concerns about effects on biota. Uncertainty among scientists as to what effects we see mean.
