Percentage depth dose at the Linac has not reached 100% on the surface and should be made an effort to treat skin cancer or skin cancer that is closer to the surface so that the maximum dose obtained cancer, one of the efforts is the use of bolus. The research reviewer feasibility of using polydimethylsiloxane as materials bolus in radiotherapy. Bolus made with a thickness of 3, 6, 9 and 12 mm with a size of 11x11 cm2, tomography image is then taken using a CT-scan to determine the CT-number that is used to calculate the density and compared to the density of mass and volume ratio. Bolus irradiated with electron 8 MeV at 100 MU for 60 seconds and measured the dose absorbed at a depth of 0; 0.5; 1.0; 1.5; 2.0 and 2.5 cm. The result of the calculation using the CT-number density is 1.24 ± 0.02 g /cm3 and the density calculation results using the ratio of the mass and volume was 1.25 ± 0.01 g / cm. Absorbed dose at the surface with the use of a bolus of 3, 6, 9 and 12 mm by 82.09%; 85.13%, 89.12% and 93.48%, while without using bolus which showed the value of absorbed dose amounted to 78.23%. Absorbed dose at a depth of 2.5 cm with the use of a bolus of 3, 6, 9 and 12 mm by 79.84%; 49.26%; 34.52% and 17.80%, while without using bolus which showed the value of absorbed dose amounted to 88.68%.These results show the density of the bolus polydimethyl siloxane has similarities with soft tissue density and may increase the dose of the surface and reduce the dose depth so polydimethyl siloxane may be one of the reference materials that can be used as a bolus in radiotherapy.

External radiotheraphy uses either symmetry or asymmetry radiation field. Percentage Depth Dose (PPD) and Dose Profile on either symmetry or asymmetry radiation field is an important parameter in conducting external therapy that is to analyze the result of parameters used for measurement, whether it is adjusted according to the specified tolerance limit. If the field size 10 X 10 cm2 is still in specified tolerance limit or it has been exceeding the limit.The techique used to collect the data was comparing whether dose distribution taken on the surface of either symmetry or asymmetry radiation field with maximum depth gained from Percentage Depth Dose (PPD) measurement and in the depth of 2 cm. By using device Linear Accelerator (LINAC) energy foton 6 and 10 MV in the radiation field with condition field no off-set and off-set 1 cm, off-set 3 cm and off-set 5 cm with Source Surface Distance (SSD) value 100 cm and in radiation field 10 X 10 cm2.The measurement result showed a change depth on Percentage Depth Dose (PPD) value in the off-set of radiation field 5 cm, on both kinds of energy caused by beam hardening, with value of symmetry and flatness 1.43% and 9.28%, for energy 6 MV and 2.2%, 6.59% for energy 10 MV. There was a change in file profile that caused declining value of flatness, and symmetry. Dose distribution because of this asymmetry radiation field should be concerned in clinical for application of asymmetry radiation field usage.

During radiotherapy treatment, critical organs are shielded using cerrobend blocks. The objective of this study was to define the minimal thickness of cerrobend blocks so that the relative absorbed dose in target less than 5%. All measurements were performed using linac Siemens/Primus Mclass 5633. Phantom relative absorbed dose were measured for square field 10 x 10 cm2. The thickness of cerrobend blocks were 2, 4, 6, 8 and 10 mm. The measurements in water were performed using compact chamber fitted with acrylic build up caps.The minimal thickness of cerrobend blocks for 5, 10 and 14 MeV electron beams are 2, 4 and 6 mm, respectively. The relative absorbed dose for phantom’s surface, maximum depth and x-ray tail using those blocks are 0.12%, 0.16%, 0.21%, 2.18%, 1.56%, 1.16%, 2.92%, 2.47% dan 1.70%.The relative absorbed dose decreases with the increasing of cerrobend block thickness and phantom depth. Therefore, if cerrobend blocks are used to protect critical organs, the thickness should be taken into account accurately.Keywords: cerrobend blocks, relative absorbed dose, electron beams

Image density is the level of film image blackness. Keywords : developer, density, pH (acidity), NaOH, Na2CO3. In this study aims to determine the pH value of the liquid developer and image density with the addition of NaOH and Na2CO3 as well as a result of the use of the developer fluid. This research is done by washing the film on the object stepwedge used the same exposure factors namely 60 kV tube voltage, time and tube current of 8 mAs. After that film development using weak developer liquid was done. To increase developer liquid’s acidity, two part of processing using 5 grams addition of NaOH and Na2CO3 on each part were done. On the first film the process was carried out by adding 5 grams of NaOH and Na2CO3 to each film on the first part of liquid. The same procedure applied using the Na2CO3. The film image density then measured by densoitometer. Result of research shows that adding NaOH and Na2CO3 to developer liquid can increase the acidity and density of film images. Adding NaOH resulted in the highest acidity level of 12,01 with the highest density level of 0,94, while adding Na2CO3 resulted in the highest acidity level of 10,49 with the highest density level of 0,93.
