Summary

Estimation of exposure from 131I inhaled from unsealed sources during laboratory procedures and from that exhaled by patients treated with 131I has revealed that the permissible levels have been exceeded by a factor of 2 - 5, although the absorbed activity was found to be between 1 and 10% of the maximum permissible absorption of 13'I inhaled through the lungs. The fall in 131I concentration in the air exhaled by 19 hyperthyroid patients, to whom 131I was administered in a dose of several hundred MBq, could be expressed by a two-component equation, which reflects the changes in 131I concentration in the blood.

Zusammenfassung

Eine Abschätzung der Strahlenbelastung durch eingeatmetes 131J aus offenen Quellen während Laborversuchen und von 131J-behandelten Patienten, die 131J ausatmeten, zeigte, daß die zulässigen Werte um einen Faktor von 2 - 5 überschritten wurden, obwohl die absorbierte Aktivität zwischen 1 bis 10% der höchstzulässigen Absorption von 131J durch die Luftwege lag. Der Konzentrationsabfall von 131J in der ausgeatmeten Luft von 19 Hyperthyreosepatienten, denen 131J in Dosen von einigen hundert MBq verabreicht worden war, konnte durch eine zweikomponentige Gleichung dargestellt werden, welche die änderungen der 131J-Konzentration im Blut widerspiegelt.
