  1. Ethics of the existing ICRP statement Deborah.Oughton@umb.no

  2. The ICRP statements ”Although the principal objective of radiation protection is the achievement and maintenance of appropriately safe conditions for activities involving human exposure, the level of safety required for the protection of all human individuals is thought likely to be adequate to protect other species, although not necessarily individual members of those species. The Commission therefore believes that if man is adequately protected then other living things are also likely to be sufficiently protected”.” (ICRP, 1977)

  3. ICRP 60 “The Commission believes that the standard of environmental control needed to protect man to the degree currently thought desirable will ensure that other species are not put at risk. Occasionally, individual members of non-human species might be harmed, but not to the extent of endangering whole species or creating imbalance between species.” (ICRP, 1991)

  4. Challenges to the Paradigm • Lack of scientific evidence to support the statements • May not be valid under some circumstances (e.g., waste disposal) • Incompatible with management of other environmental stressors • Requirement for assessment under some national legislation • Philosophically inadequate and outdated

  5. Consensus Statement – Oslo 2001 (excerpt) • As part of the effort to revise and simplify the current system of radiological protection for humans, there is a need to address specifically radiological protection of the environment. • Our present level of knowledge should allow the development of a system that can be used to logically and transparently assess protection of the environment using appropriate end points. The development of the system ought to identify knowledge gaps and uncertainties that can be used to direct research to improve the system.

  6. ”Menace of the Nuclear Rabbits”* * Scotsman headline 12/6/2003 • Rabbits burrowing in the Dounreay nuclear waste pits • Might be radioactive • Might be eaten by cats, humans, other wildlife • Bye bye bunnys…

  7. Backlash • ”Protecting humans HAS protected the environment … show us the evidence that it has not” • ”We know enough to be able to claim the risks are small” • ”There are more important threats to the environment” • ”We have better things to spend our money on”

  8. Is the statement scientifically robust? • ”The Commission believes that: “... if man is adequately protected then other living things are also likely to be sufficiently protected” (ICRP, 1977) “… the standard of environmental control needed to protect man to the degree currently thought desirable will ensure that other species are not put at risk.”(ICRP, 1991)

  9. Is the statement scientifically robust? • ”We know more today than we did in 1977 and 1990” ”…but we also know what we don’t know (large data gaps on transfer and effects)” • Do we know enough to conclude that there is no need to regulate specifically for non-human species. Will control of human exposures always be sufficient to protect the environment? • Can we convince stakeholders that our assessment is robust enough? • How can we best demonstrate that the environment is not at risk from ionising radiation?

  10. A satisfactory degree of protection? “..individual members of non-human species might be harmed but not to extent of endangering whole species or creating imbalance between species.” (ICRP, 1991)

  11. What are we protecting and why? Pollution control Resource exploitation Nature conservation

  12. Leave the flowers for others to enjoy! Let the flowers live!

  13. What is a satisfactory degree of protection? • Ecosystem function • Biodiversity • Protected species and habitats? • The abiotic environment? Ecosystem complexity raises challenges for any environmental stressor

  14. There are more important threats to the environment • “The impact of ionising radiation is negligible compared to other changes” • ”We know more about ionising radiation than many other environmental stressors” • ”We haven’t seen any adverse effects so it is safe to assume there are none” • How can we best demonstrate that the risks are lower than other environmental threats? • Are the proposed assessment and management methods compatible?

  15. The costs of regulation outweigh the benefits • ”We could be spending money more effectively” • ”We are discriminating against the nuclear industry” • What are the costs and how might they be optimised? • What are the benefits?
