  1. A cohort study with regard to the risk of haematological malignancies in patients treated with x-rays for benign lesions in the locomotor system. II : Estimation of absorbed dose in the red bone marrow.

    Article - En anglais

    A cohort study with regard to the risk of haematological malignancies was performed on about 20 000 patients who in 1950-1964 received roentgen treatment for benign conditions in the locomotor system.

    In order to estimate the mean absorbed red bone marrow dose the treatments were classified as concerning 10 sites (cervical spine, thoracic spine, lumbar spine, sacral region, shoulder, hip, elbow, wrist, knee and ankle).

    The four last-mentioned sites do not normally contain red bone marrow in adults and their contribution to the mean absorbed dose was regarded as zero.

    For the other 6 sites random samples consisting of 30 patients for each site were drawn from the cohort.

    By use of the treatment records and data from the literature on some physical parameters and red bone marrow distribution in normal adult persons, average conversion factors were calculated by which the subscribed surface dose could be converted into mean absorbed dose in red bone marrow.

    These conversion factors were then applied on the whole cohort and used for stratification of it according to different levels of exposure.
