The accuracy of in vivo dose measurements during Cobalt-60 total body irradiation

, : The accuracy of in vivo dose measurements during Cobalt-60 total body irradiation. Neoplasma 50(1): 74-78

The purpose of this study was to check the agreement between the doses measured during total body irradiation and those previously calculated. The irradiation was performed with the use of lateral and anterior-posterior fields. The lungs were shielded during the anterior-posterior fields only when followed by an electron boost applied to the thorax wall. A cobalt-60 source was used in eight fractions on four consecutive days. Thermoluminscent, semiconductor detectors and ionisation chambers were used for in vivo measurements at several reference points on the body. The agreement between the calculated and measured doses was tested at the p=0.05 level with the use of a Student's test for a group of thirty patients.

The purpose of this study was to investigate whether propofol has a neuroprotective effect on the fetal brain after intrauterine ischemia-reperfusion (I/R) injury in the rat fetus. Fetal brain ischemia was induced by clamping the utero-ovarian art...
