The ICRU recommendations for reporting intracavitary therapy in gynaecology and the Manchester method of treating cancer of the cervix uteri.

The recommendations of the International Commission on Radiation Units and Measurements for reporting intracavitary therapy have been considered with particular regard to the Manchester method of treating cancer of the cervix uteri. The total reference air kerma is calculated and tabulated as a function of prescription for the standard Manchester applicator arrangements. Furthermore, it is shown that the volume contained within a particular isodose surface may be determined, with very acceptable accuracy, from the total reference air kerma by the use of a simple empirical expression.
