The emitter discharge is affected by parameters such as pressure, irrigation water temperature, manufacturer’s coefficient of variation, and emitter clogging. In order to study the effects of irrigation water temperature on emitter discharge and to determine the discharge-pressure variations and manufacturer’s coefficient of variations, an experimental trickle irrigation system was designed and...

Radioisotopes that emit electrons (beta particles), such as radioiodine, can effectively kill target cells, including cancer cells. Aqueous 32P[PO4] is a pure beta-emitter that has been used for several decades to treat non-malignant human myeloproliferative diseases. 32P[PO4] was directly compared to a more powerful pure beta-emitter, the clinically important 90Y isotope. In vitro, 32P[PO4] wa...
introduction:targeted radionuclide therapy (trt) has been demonstrated to be an effective therapeutic tool in patients with disseminated bone metastasis. trt is generally performed with a single radionuclide. in this study we investigated the feasibility of combined trt with a high-energy beta emitter (153sm) and a low energy beta emitter (177lu) in wistar rats. methods: the cocktail complex of...
NHL is the most common hematologic cancer in adults. Rituximab is the FDA approved treatment of relapsed or refractory low grade B-cell Non-Hodgkin Lymphoma (NHL). But patients eventually become resistant to rituximab. Since lymphocytes and lymphoma cells are highly radiosensitive, low grade NHL that has relapsed or refractory to standard therapy is treated by RIT in which a beta-emitting radio...
background: the formalism recommended by task group 60 (tg-60) of the american association of physicists in medicine (aapm) is applicable for β sources. radioactive biocompatible and biodegradable 153sm glass seed without encapsulation is a β- emitter with a short half life and delivers a high dose rate to the tumor in the millimeter range. in this work the dosimetry parameters of the seed for ...
