Direct Determination of the Body Content of Radionuclides (Report 69)

Previous ICRU reports have dealt with the formulation and properties of tissue substitutes and phantoms that are used to calibrate in vivo measurement systems. This report provides guidance on the overall process of the direct measurement of radionuclides in the human body for radiation protection and medical applications.

Retrospective Assessment of Exposure to Ionising Radiation (Report 68)

Basic dose quantities used in dose reconstruction are defined. The following dose -reconstruction methods based on measurements performed for individual persons are reviewed: electron paramagnetic resonance (EPR) measurements with tooth enamel, analyses of dicentric chromosomes and chromosome translocations, counting of micronuclei in lymphocytes, somatic mutation assays, and measurements of radionuclide activities in the human body.

Absorbed-Dose Specification in Nuclear Medicine (Report 67)

A number of reasons have led to a reappraisal of dose specification for nuclear medicine. These include an appreciation of non-uniformities in the distribution of radioactivity in the body, at all levels, for even the most common diagnostic and therapeutic agents; an increasing need to deal with the complexities of varying dose rates; the imperative to provide individual rather than standardised dose estimates as targeted radio-nuclide therapy becomes more sophisticated; as well as improvements in technology.

Determination of Operational Dose Equivalent Quantities for Neutrons (Report 66)

This Report provides guidance for the measurement of the operational dose equivalent quantities for neutron radiation, taking into account the recommendations of ICRP Publication 60.

Quantities, Units and Terms in Radioecology (Report 65)

This Report provides the first comprehensive and authoritative set of definitions for quantities, units and terms used in the highly interdisciplinary field of radioecology. The scope of this report is the presentation of the primary quantities and terms that are used in studies of radionuclide transport in the environment and those used to help assess the effects of environmental radioactivity on plants, animals and humans.

Dosimetry of High-Energy Photon Beams Based on Standards of Absorbed Dose to Water (Report 64)

This Report examines the methods by which absorbed dose to water can be determined for photon radiations with maximum energies from approximately to 1 MeV to 50 MeV, the beam qualities most commonly used for radiation therapy.
