What Is This Tool?
This converter allows you to transform radiation absorbed dose measurements from gray (Gy) to hectogray (hGy), facilitating simpler expression of high-dose radiation values used in various fields such as radiotherapy, industrial processing, and dosimetry.
How to Use This Tool?
- Enter the absorbed radiation dose value in gray (Gy) into the input field
- Select gray (Gy) as the starting unit and hectogray (hGy) as the target unit
- Click the convert button to see the equivalent dose in hectogray (hGy)
- Review the converted value which simplifies large absorbed dose reporting
Key Features
- Converts absorbed dose values between gray (Gy) and hectogray (hGy)
- Based on the exact relationship: 1 Gy equals 0.01 hGy
- Supports radiation dose units used in medical and industrial contexts
- Helps express large radiation doses in a more manageable format
- Browser-based tool requiring no installation
Examples
- Converting 50 Gy results in 0.5 hGy
- Converting 200 Gy results in 2 hGy
Common Use Cases
- Prescribing and documenting therapeutic doses in external beam radiotherapy or brachytherapy
- Calibrating and testing radiation detectors and dosimeters in medical and industrial environments
- Reporting doses in industrial radiation processes like sterilization and material modification
- Performing radiation-hardness testing of electronics and materials at high absorbed doses
- Assessing high-dose events in accident dosimetry and specialized laboratory calibrations
Tips & Best Practices
- Use this conversion for large dose values to simplify numeric representation
- Do not use hectogray for low-dose measurements where smaller units are required
- Remember that absorbed dose units do not indicate biological effects without further weighting
- Cross-check conversions when documenting doses in medical or safety-critical applications
Limitations
- Hectogray units are unsuitable for low absorbed dose quantities due to their large scale
- Absorbed dose units alone do not reflect biological effects and need additional factors for conversion to units like sieverts
- This tool does not provide biological dose assessment or radiobiological weighting
Frequently Asked Questions
- What is the relationship between gray and hectogray?
- One gray equals 0.01 hectogray, meaning 100 grays make one hectogray.
- Can I use this tool for low radiation doses?
- No, the hectogray unit is too large for low-dose measurements and is better suited for high-dose scenarios.
- Does converting absorbed dose units indicate biological radiation effects?
- No, absorbed dose units like gray and hectogray measure physical energy deposited, and biological effects require additional weighting factors.
Key Terminology
- Gray [Gy]
- The SI unit quantifying absorbed ionizing radiation dose, defined as one joule of radiation energy deposited per kilogram of matter.
- Hectogray [hGy]
- An SI-derived unit of absorbed radiation dose equal to 100 grays, used to represent very large absorbed doses more conveniently.
- Absorbed Dose
- The amount of energy from ionizing radiation deposited per unit mass of material or tissue.
