[Development of new, more effective radiation protection methods for radium-treated patients and report of two of our most unusual cases].

In year 1936 was opened in Budapest the Loránd Eötvös Radium and Röntgen Institute having 2 Ci radium in many tubes and needles. In the first years the occupational gamma exposure of persons working in the gynecological department and in the health physical laboratory was very high, because the maximum permissible dose recommended by the ICRP in 1928 was 1.5 R/week. With the developing of new radiation protection equipments was the absorbed dose strongly decreased. A physician and a physicist received total more than 2-times higher dose, than the permissible newest dose limit, but they are now 86 and 87 year old and without any radiation detriment, in good health. Similar publications with such long continually measured dose data, was not found in the literature.
