Examples
-
5 centigray converts to 50000 microgray (5 × 10000 µGy).
-
0.2 centigray converts to 2000 microgray (0.2 × 10000 µGy).
Common Use Cases
-
Prescribing and documenting radiation doses in external beam radiotherapy treatment plans.
-
Reporting absorbed doses in nuclear medicine and brachytherapy procedures.
-
Monitoring low-level environmental radiation or workplace exposure with survey instruments.
-
Evaluating radiation doses from diagnostic imaging, including dental and chest x-rays.
-
Assessing cosmic-ray and secondary radiation exposure for aviation or spacecraft personnel.
Tips & Best Practices
-
Ensure consistent unit use when converting and interpreting radiation doses.
-
Use sensitive measurement tools when working with microgray values due to their small magnitude.
-
Verify dose distribution uniformity when applying conversions in heterogeneous materials.
-
Double-check converted values especially when used for critical medical or safety decisions.
Limitations
-
Requires careful maintenance of unit consistency and precision during conversion.
-
Microgray values represent very small doses that often need sensitive instrumentation to measure accurately.
-
Assumes absorbed doses are evenly distributed per unit mass, which may not hold in all tissues or materials.
Frequently Asked Questions
-
What is the conversion factor from centigray to microgray?
-
1 centigray (cGy) is equal to 10,000 microgray (µGy).
-
In which fields is converting cGy to µGy commonly applied?
-
This conversion is commonly used in medical physics, radiotherapy planning, diagnostic radiology, environmental radiation monitoring, and aerospace radiation safety.
-
Why must care be taken when converting to microgray units?
-
Because microgray values are very small, precise measurement and unit consistency are crucial, especially in sensitive applications involving heterogeneous tissues or materials.
Key Terminology
-
Centigray (cGy)
-
Unit of absorbed ionizing radiation dose equal to one hundredth of a gray, used in radiotherapy and medical physics.
-
Microgray (µGy)
-
SI derived unit of absorbed dose equal to one millionth of a gray, used for low-level radiation monitoring.
