Study of entrance surface skin dose in veterinary radiology
This study aims the evaluation of the radiation dose levels involved in veterinary radiology and to contribute to review the procedures for performing radiographic exams in animals in the Department of Veterinary Radiology ...
Developing new radiotherapy techniques using linac based gamma radiation sources
A major challenge in cancer radiotherapy is to deliver a lethal dose of radiation to the target volume while minimizing damage to the surrounding normal tissue. We have proposed a model on how treatment efficacy might be ...
Measurement of orthovoltage X-ray intensity with a lithium niobate transducer
A microcontrolled instrument for measuring the energy fluence rate (or intensity) of X-ray pulses in the orthovoltage range of 120 to 300 kV is described. The prototype instrument consists of a pyroelectric sensor, a ...
Feed variation and biometrical factors in tilapias (Oreochromis niloticus) exposed to 60Co gamma radiation
Ionizing radiation has been widely used for cancer treatment and diagnostic exams in medicine, besides being used in the fields of energy generation and industry. This work aimed to verify the occurrence of biological ...
The use of planarians as in vivo animal model to study laser biomodulation effects
A variety of effects is attributed to the photo stimulation of tissues, such as improved healing of ulcers, analgesic and anti-inflammatory effects, stimulation of the proliferation of cells of different origins and ...
