Frequently Asked Questions
What is the difference between Gray (Gy) and Sievert (Sv)?
Gray measures absorbed radiation dose (energy deposited per mass), while Sievert measures equivalent dose that accounts for biological effects based on radiation type and tissue sensitivity.
Why are there both traditional and SI radiation units?
Traditional units (rad, rem, curie) were developed earlier and are still used in some countries, particularly the US. SI units (gray, sievert, becquerel) are the international standard used in most countries and scientific publications.
Is my data kept private when I use this converter?
Absolutely. All calculations happen locally in your browser. Your radiation dose values are never sent to any server, meaning we never see, store, or have access to your data. It is 100% secure and private.
Can I use this tool on my mobile device?
Yes, our website and converter are fully responsive and optimized to work perfectly on all devices, including smartphones and tablets.
Are the conversion factors accurate for medical applications?
Yes, we use standard conversion factors accepted in medical physics and radiation protection. However, for critical medical decisions, always verify with qualified medical physicists.
Why Choose Our Radiation Dose Converter?
Our online radiation dose converter stands out from other tools because of its comprehensive coverage, accuracy, and privacy features. Unlike many online converters, we don't process your data on our servers - all calculations happen in your browser. This means your sensitive radiation dose data, patient information, and research data remain completely private. The tool also works offline once loaded, making it reliable even with unstable internet connections.
Common Applications of Radiation Dose Conversion
Radiation dose conversion has numerous practical applications across various fields:
- Medical Radiology: Convert between different dose measurement systems for diagnostic and therapeutic applications
- Radiation Protection: Ensure compliance with international safety standards and regulations
- Research & Development: Standardize radiation measurements across different research studies and publications
- Education & Training: Teach students the relationships between different radiation units and measurement systems
- Nuclear Industry: Convert operational radiation measurements for safety monitoring and reporting
Understanding Radiation Units
Radiation measurement involves several different types of units, each serving a specific purpose:
- Absorbed Dose (Gray, Rad): Measures the energy deposited by radiation in any material
- Equivalent Dose (Sievert, Rem): Accounts for the biological effectiveness of different radiation types
- Exposure (Roentgen): Measures ionization in air from X-rays or gamma rays
- Radioactivity (Becquerel, Curie): Measures the rate of radioactive decay
