Development of Indigenous Source of Cobalt Suitable for Radiation Technology Applications
The role of Cobalt-60 as a radiation source in teletherapy for the treatment of cancer needs hardly to be reiterated. Although not used commonly in developed countries, cobalt-60 teletherapy machines can still be regarded as a very viable and cost effective option for the treatment of a sizeable fraction of cancer patients. At present in India, there are only 399 teletherapy units (280 telecoba...
متن کاملDosimetric Conformity of Cobalt-60 (Co) Beams
Objective: The radiation dosimetry is the output measurement of radiation generating source/ machine and its ambition is to ensure that the teletherapy units’ outputs are within limits. In the current article, the dosimetry of Cobalt-60 (Co 60 ) teletherapy units at Nuclear Institute of Medicine and Radiotherapy (NIMRA), Jamshoro Pakistan was studied. As Co 60 is undergo decay process, the outp...
متن کاملDosimetric Consistency of Co-60 Teletherapy Unit- a ten years Study.
OBJECTIVE The goal of the Radiation standards and Dosimetry is to ensure that the output of the Teletherapy Unit is within ±2% of the stated one and the output of the treatment dose calculation methods are within ±5%. In the present paper, we studied the dosimetry of Cobalt-60 (Co-60) Teletherapy unit at Sher-I-Kashmir Institute of Medical Sciences (SKIMS) for last 10 years. Radioactivity is th...
متن کاملModel for Estimating Power and Downtime Effects on Teletherapy Units in Low-Resource Settings
Purpose More than 6,500 megavoltage teletherapy units are needed worldwide, many in low-resource settings. Cobalt-60 units or linear accelerators (linacs) can fill this need. We have evaluated machine performance on the basis of patient throughput to provide insight into machine viability under various conditions in such a way that conclusions can be generalized to a vast array of clinical scen...
متن کاملEstimating the radiation dose of non-radiation workers from nuclear medicine patients
Introduction: As a valuable imaging modality, Nuclear Medicine (NM) indications is raising in clinical practice. The remained portion administrated radioactive material in patients’ tissues is a critical issue, especially when the procedure is performed in hospitalized patients, where the non-radiation workers present. The aim of this study was evaluation the dose of non-radia...
