We mcasured the scattered radiation around the various kinds of flunroscopy tables with Pocketchambers or Ionizationchambers survey meter. A Phantom or a Patient's body was the some of the s.r. of which the back s.r. was the softs and strongest. To protec〓 the back s.r. we studied the effect of a aluminium plate placed under the table and coneluded that a Al plate of 1mm thickness could reduce the back s.r. to about 50%. A new type of tables, which had the iron plate and lead gummy shcets around the patient's body, was proved to be completely safe as regard to the present softy standard.
