What Is This Tool?

This tool converts absorbed radiation dose measurements from the SI-derived hectogray (hGy) unit to the legacy rad (rd) unit. It facilitates translating dose values for industrial, medical, and regulatory purposes.

How to Use This Tool?

  • Enter the dose value in hectogray (hGy) to convert.
  • Select hectogray as the input unit and rad as the output unit.
  • Click the convert button to see the equivalent dose in rad (rd).

Key Features

  • Converts radiation dose from hectogray (hGy) to rad (rd).
  • Quickly interprets large-dose values in legacy units.
  • Supports industrial, medical, and dosimetry applications.
  • Provides straightforward usage with clear input and output.

Examples

  • Convert 2 hGy: 2 × 10000 rd = 20000 rd.
  • Convert 0.5 hGy: 0.5 × 10000 rd = 5000 rd.

Common Use Cases

  • Interpreting high doses in industrial radiation processing and sterilization.
  • Radiation-hardness testing of electronics and materials with high absorbed doses.
  • Analyzing historical medical radiotherapy doses reported in legacy units.
  • Compliance with environmental and occupational radiation protection standards.

Tips & Best Practices

  • Always document conversions clearly to avoid unit confusion.
  • Use hectogray values for SI-consistent dose reporting when possible.
  • Be cautious when interpreting large dose magnitudes across unit systems.

Limitations

  • The rad is a non-SI legacy unit, which may cause confusion if not properly noted.
  • High precision doses are better expressed in gray units for SI coherence.
  • Converting large doses requires attention to the scale difference between units.

Frequently Asked Questions

What does 1 hectogray equal in rad?
One hectogray equals 10,000 rad, reflecting the difference between the SI unit gray and the legacy rad unit.

Why convert absorbed dose units from hectogray to rad?
Conversion helps interpret historical dose data, meet legacy regulatory requirements, and maintain compatibility with older radiation protection records.

Is the rad unit still widely used?
The rad is largely a legacy unit but remains in use in some occupational and environmental dose reporting contexts.

Key Terminology

Hectogray (hGy)
An SI-derived unit of absorbed ionizing radiation dose equal to 100 grays, representing energy absorption per kilogram of matter.
Rad (rd)
A legacy unit of absorbed radiation dose equal to 0.01 gray, used to quantify energy deposited per unit mass.
