What Is This Tool?

This converter transforms radiation absorbed dose values from the legacy unit rad (rd) to the extremely small unit femtogray (fGy), facilitating detailed analysis of energy deposition by ionizing radiation at microscopic scales.

How to Use This Tool?

  • Enter the radiation absorbed dose value in rad (rd)
  • Select rad as the input unit and femtogray (fGy) as the output unit
  • Click convert to see the equivalent absorbed dose expressed in femtograys
  • Review the results for detailed microscopic or single-event energy deposition analysis

Key Features

  • Converts rad (rd) to femtogray (fGy) based on established conversion rate
  • Supports precise translation of legacy and fine-scale radiation dose measurements
  • Ideal for microdosimetry, radiobiology, and ultra-sensitive detector calibration
  • Browser-based and easy to use without requiring additional software

Examples

  • 2 Rad [rd] equals 2 × 10^13 Femtogray [fGy] (20000000000000 fGy)
  • 0.5 Rad [rd] equals 0.5 × 10^13 Femtogray [fGy] (5000000000000 fGy)

Common Use Cases

  • Converting legacy radiotherapy doses and interpreting historical medical records
  • Radiation protection and dose reporting where non-SI units remain in use
  • Microdosimetry experiments measuring single-cell or subcellular radiation effects
  • Calibration of ultra-sensitive radiation detectors and low-background instrumentation
  • Analysis of radiation effects on microelectronics in space or particle physics

Tips & Best Practices

  • Ensure numerical accuracy due to the large unit magnitude difference
  • Use this conversion to support detailed microscopic or single-event radiation analysis
  • Be cautious converting very small femtogray values as they may exceed practical measurement limits
  • Prefer SI units like gray and its derivatives for consistency in most modern applications

Limitations

  • Rad is a legacy non-SI unit with declining use in favor of gray-based units
  • Extreme scale difference can lead to numerical or interpretation errors
  • Very small femtograys might be beyond measurement resolution in practical scenarios

Frequently Asked Questions

What does one rad measure?
One rad (rd) is an older unit measuring absorbed ionizing radiation dose, equal to 0.01 gray, quantifying energy deposited per mass.

Why convert from rad to femtogray?
Conversions enable analysis at a microscopic or single-event level, important for radiobiology, detector calibration, and detailed radiation studies.

Are femtograys commonly used in everyday radiation measurements?
Femtogray measures extremely tiny doses and is typically used in specialized fields like microdosimetry and research rather than routine dose monitoring.

Key Terminology

Rad [rd]
A legacy unit of absorbed ionizing radiation dose equal to 0.01 gray, representing energy deposited per kilogram of matter.
Femtogray [fGy]
An extremely small SI unit of absorbed dose equal to 10^-15 gray, quantifying tiny radiation energy depositions at microscopic scales.
Gray [Gy]
SI unit of absorbed radiation dose representing one joule of radiation energy deposited per kilogram of matter.
