Centigray: Unraveling the Mysteries of Radiation Measurement

Understanding Centigray: A Primer

Centigray (cGy) is a unit of measurement used to quantify the absorbed dose of ionizing radiation in a medium. It represents the amount of energy deposited by radiation per unit mass of the irradiated material. A cGy is equivalent to 10^-2 Gray (Gy), the SI unit for absorbed dose.

Applications of Centigray in Radiation Therapy

In radiation therapy, cGy is a crucial parameter for planning and delivering treatments. It is used to:

Determine the radiation dose: The total dose prescribed for a particular treatment is typically expressed in cGy.
Monitor patient exposure: Radiation exposure during therapy is measured in cGy to ensure safety and prevent overexposure.
Calibrate treatment equipment: Radiation therapy units are calibrated using cGy to ensure accurate dose delivery.

Biological Effects of Centigray

The biological effects of radiation vary with the absorbed dose. At low doses (less than 10 cGy), radiation can stimulate cell growth and immune function. However, higher doses can cause cell damage, tissue necrosis, and cancer development.
