HC Deb 14 February 2000 vol 344 cc380-1W
Mr. Livsey

To ask the Secretary of State for Health (1) what figures were used to represent concentrations of uranium in air in the calculations of radiation doses from plutonium to the tracheo-bronchial lymph nodes of people aged up to 25 years resident in the village of Seascale in Cumbria, which were supplied by the National Radiological Protection Board to the Committee on Medical Aspects of Radiation in the Environment; [106816]

(2) what figures were used to represent concentrations of plutonium in air in the calculation of radiation doses from plutonium to the tracheo-bronchial lymph nodes of people aged up to 25 years resident in the village of Seascale in Cumbria, which was supplied by the National Radiological Protection Board to the Committee on Medical Aspects of Radiation in the Environment; [106811]

(3) what (a) theoretical modelling of plutonium concentrations and (b) post mortem measurements of plutonium were used in the calculation of radiation doses from plutonium to the tracheo-bronchial lymph nodes of people aged up to 25 years resident in the village of Seascale in Cumbria, which was supplied by the National Radiological Protection Board to the Committee on Medical Aspects of Radiation in the Environment; [106815]

(4) what (a) theoretical modelling of uranium concentrations and (b) post mortem measurements of uranium were used in the calculation of radiation doses from uranium to the tracheo-bronchial lymph nodes of people aged up to 25 years resident in the village of Seascale in Cumbria, which was supplied by the National Radiological Protection Board to the Committee on Medical Aspects of Radiation in the Environment; [106810]

(5) what figure was used to represent the mass of the tissue considered to be the target organ in the calculation of radiation doses from plutonium to the tracheo-bronchial lymph nodes of people aged up to 25 years resident in the village of Seascale in Cumbria, which was supplied by the National Radiological Protection Board to the Committee on Medical Aspects of Radiation in the Environment; [106814]

(6) what air intake particles were used as the basis for the calculation of radiation doses from plutonium to the tracheo-bronchial lymph nodes of people aged up to 25 years resident in the village of Seascale in Cumbria, which was supplied by the National Radiological Protection Board to the Committee on Medical Aspects of Radiation in the Environment; [106812]

(7) what figures were used to represent the radioactivity of (a) plutonium, (b) uranium and (c) other man-made isotopes, incorporated within the tracheo-bronchial lymph nodes of people aged up to 25 years resident in the village of Seascale in Cumbria, in the calculation of doses from plutonium to the tracheo-bronchial lymph nodes of those people which was supplied by the National Radiological Protection Board to the Committee on Medical Aspects of Radiation in the Environment.
