What Is This Tool?

This converter transforms absorbed radiation dose measurements from rad (a legacy unit) to kilogray (a modern SI unit). It aids in translating legacy doses into high-dose contexts such as industrial radiation processing and dosimetry.

How to Use This Tool?

  • Enter the absorbed dose value in rad [rd]
  • Select the target unit as kilogray [kGy]
  • Click the convert button to see the equivalent dose in kilogray

Key Features

  • Easy conversion between rad and kilogray units of radiation absorbed dose
  • Supports interpretation of legacy medical and radiation protection records
  • Facilitates dose reporting in industrial, pharmaceutical, and food irradiation contexts

Examples

  • 100 rad [rd] converts to 0.001 kGy
  • 50,000 rad [rd] converts to 0.5 kGy

Common Use Cases

  • Interpreting historical radiotherapy doses in modern terms
  • Reporting radiation protection and occupational dose using SI units
  • Converting absorbed dose data for industrial sterilization processes
  • Evaluating food irradiation and polymer modification treatments

Tips & Best Practices

  • Always confirm the radiation context before converting values
  • Use this tool to bridge legacy and modern unit systems for clearer communication
  • Double-check large-scale conversions to prevent misinterpretation of dose magnitude

Limitations

  • Rad is a non-SI, legacy unit and may lack precision in high-dose settings
  • Kilogray measures very high absorbed doses; small rad values convert to very small kGy values which can be misread
  • Conversion assumes uniform energy deposition and does not consider specific radiation qualities or biological impacts

Frequently Asked Questions

Why convert rad to kilogray?
Converting rad to kilogray updates legacy dose measurements into SI units useful for industrial and modern radiation applications.

What is the conversion rate from rad to kilogray?
One rad equals 0.00001 kilogray according to the established conversion.

Can this converter be used for all radiation dose measurements?
It is appropriate for absorbed dose units, but the rad is legacy and kilogray is for high doses, so context must be considered.

Key Terminology

Rad [rd]
A legacy unit of absorbed dose of ionizing radiation equal to 0.01 gray, representing energy deposited per unit mass.
Kilogray [kGy]
An SI-derived unit of absorbed radiation dose equal to 1,000 grays, used for quantifying high ionizing radiation doses.
Absorbed Dose
The amount of energy deposited by ionizing radiation per unit mass of matter.
