ABSTRACT: The medical X-ray diagnostics is the dominant
„man-made” source of radiation exposure to the Bulgarian population. The
aim of this study is to evaluate the relationship between exposure from
medical X-ray diagnostic procedures and the occurrence at the myeloid leukemia.
The assessment is based on analytical epidemiological study of a case-control
type. Investigation was made on 132 cases with acute and chronic myeloid
leukemia and 264 controls matched by sex and age. The risk factor assessment
is based on the red bone marrow dose (mSv) cumulated from the different
X-ray diagnostic procedures as well as on the distribution of investigated
persons depending on the type and number of procedures. The results from
the present study prove the impact of X-ray diagnostics as a risk factor
to myeloid leukemia.
