Determination of Dose Equivalents from External Radiation Sources--Part II (Report 43)

ICRU Report No. 43 is the second in a three-report series produced by the ICRU to provide guidance on the practical determination of dose equivalents from external radiation sources. The first of the series, ICRU Report 39, Determination of Dose Equivalents from External Radiation Sources, provided definitions of quantities to be employed in radiological protection monitoring, including the ambient dose equivalent, the directional dose equivalent, the individual dose equivalent penetrating, and the individual dose equivalent superficial. Report 43 provides the grounds for the Commission=s selection of these quantities and the basis for their definition.


Use of Computers in External Beam Radiotherapy Procedures with High Energy Photons and Electrons

This Report continues the series of reports issued by the Commission dealing with dosimetric problems in external beam therapy with high energy photons. The previous reports covered such matters as the measurement of absorbed dose in a water phantom, determination of absorbed dose in the patient and specification of target absorbed dose for reporting purposes. Since the publication of those ICRU reports, computers have assumed an increasingly important role in dosimetric and treatment planning procedures in many radiation therapy centers. more

Modulation Transfer Function of Screen- Film Systems (Report 41)

This Report reviews and describes various concepts used in the analysis of the physical aspects of radiographic image quality for the screen-film systems used in diagnostic radiology. more

The Quality Factor in Radiation Protection (Report 40)

This Report is the report of a joint task group of the ICRU and the International Commission on Radiological Protection to the two Commissions. It represents the culmination of an effort that the Commissions initiated when radiobiological findings indicated that protection recommendations for some high-LET radiations might not offer the same margin of safety as those for low-LET radiations. more

Determination of Dose Equivalents Resulting from External Radiation Sources (Report 39)

ICRU Report No. 39 is the first of what will be a series of ICRU documents treating methods for determining the dose equivalents resulting from exposure to sources external to the body. The Report states definitions of quantities to be employed in the monitoring of ionizing radiation that provide a basis for effective radiation protection.


Dose and Volume Specification for Reporting Intracavitary Therapy in Gynecology (Report 38)

This Report deals with the problem of dose and volume specification with prinicpal emphasis on gynecological applications. The concepts developed in the Report are, however, designed to be applicable to other types of intracavitary applications.
