where, the EBRT of total dose 50 Gy (Gray) in 25 fractions, 200 cGy
(centigray) per fraction daily for 5 days a week was given with linear accelerator along with injection cisplatin 35 mg/[m.sup.2] intravenous over 1 h infusion was given weekly during EBRT course.
The Elekta Precise Clinical Linear Accelerator was calibrated using a large water phantom before this study was done using a 6 MV photon beam to give 100 cGy
(1 Gy) at 100 MU with a pre-calibrated NE 2570/1 Farmer-Type Ionization Chamber to determine the absorbed dose.
We further investigated if the CG-rich oxidized cfDNA penetrates into cells after treating them with 10 cGy
Irradiation was accomplished at a dose of 1000 cGy
from a 60Co source at a distance of 80 cm at a rate of 96 cGy/min.
The computer-based calculated dose within entire PTV ranged from 99.7 to 101.6 cGy
, and the dose inhomogeneity was 1.9% within the PTV.
Patient radiation dose was expressed in terms of total [P.sub.KA] in cGy
En el tratamiento con iridio 192 sin plomo, dosis de 300 cGy
y un aplicador de contacto prescrito a 1,5 cm, se encontro un conteo de 51.676 pixeles donde el minimo fue 115 y el maximo 169.
(2,6,7) Vale ressaltar que a dose de radiacao, com protecao abdominal adequada, fica em torno de 0,004 cGy
, sendo insignificante o risco fetal.

The dose of radiation administered was 11.7 cGy
per scan, as measured by dosimeter.
Total radiation dose varied from 6000 cGy
to 7920 cGy
(mean 6900 cGy
, median 7000 cGy
Adjuvant therapy with 5-flourousil and gemcitabine for 6 months andradiotherapywiththe dose of 4500 cGy
for 5 were decided to be given to the patient.
