What does femtogray measure?

Femtogray measures extremely small absorbed radiation doses, quantifying ionizing radiation energy deposition at microscopic or single-event levels.

What is the relationship between femtogray and joule per kilogram?

1 femtogray equals 1 × 10⁻¹⁵ joule per kilogram, linking ultrasmall absorbed doses to the standard SI unit of radiation dose.

In which fields is this conversion most commonly used?

It is widely used in microdosimetry, radiobiology, radiation detector calibration, radiotherapy planning, health physics, space radiation studies, and particle physics.

Tips & Best Practices

Ensure measurements are performed with precise and sensitive instrumentation due to the small scale of femtograys
Use consistent units when comparing or reporting radiation doses
Understand the context of energy deposition, as microscopic dose distributions can be complex
Apply appropriate calibration protocols when working with detector data
Leverage the conversion to interpret microscopic dose data within standard dosimetry frameworks

Limitations

The femtogram unit represents extremely small doses requiring careful measurement techniques
Assumes uniform energy deposition which may not reflect complex microdose distributions
Conversion accuracy depends on the quality of the input data and instrumentation used
