What is the frequency of checking the output of Cobalt 60 beam?

The frequency of checking the output of a Cobalt-60 beam is typically recommended to be monthly. This regular monitoring is essential to ensure that the radiation output remains consistent and within the specified parameters. Monthly checks allow for prompt identification of any deviations that might affect treatment delivery, ensuring patient safety and treatment efficacy.

Cobalt-60 units can experience changes in output over time due to various factors such as decay of the radioactive source, machine wear, and other operational variables. Checking the output monthly helps maintain compliance with safety and regulatory standards while ensuring that the dosimetry calculations are accurate and reliable.

While daily checks are too frequent and may not provide additional benefits versus resource utilization, weaker frequencies such as weekly, quarterly, or annual checks may not sufficiently capture any fluctuations or changes in output that could affect treatment planning and delivery, potentially leading to inaccuracies in dosage received by patients.
