1. What is Absorbed Dose?

Absorbed dose is a measure of the energy deposited by ionizing radiation in a unit mass of matter. The SI unit for absorbed dose is the Gray (Gy), where 1 Gy = 1 Joule per kilogram.

2. How Does the Calculator Work?

The calculator uses the absorbed dose formula:

Where:

• \( D \) — Absorbed dose (Gray, Gy)
• \( E \) — Energy absorbed (Joules, J)
• \( m \) — Mass of absorbing material (kilograms, kg)

Explanation: The formula calculates how much energy is deposited per unit mass of the absorbing material.

3. Importance of Absorbed Dose Calculation

Details: Absorbed dose is fundamental in radiation protection, radiotherapy treatment planning, and assessing radiation effects on materials and biological systems.

4. Using the Calculator

Tips: Enter energy in Joules and mass in kilograms. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between absorbed dose and equivalent dose?
A: Absorbed dose measures energy deposited, while equivalent dose accounts for radiation type by applying radiation weighting factors.

Q2: What are typical absorbed dose values?
A: Background radiation is about 0.002-0.01 Gy/year. Radiotherapy treatments may deliver 1-80 Gy depending on the treatment.

Q3: How is absorbed dose measured?
A: It can be measured using ionization chambers, calorimeters, or calculated using Monte Carlo simulations.

Q4: What materials is this calculation valid for?
A: The basic calculation applies to any material, though different materials absorb radiation differently in practice.

Q5: How does absorbed dose relate to biological effects?
A: Biological effects depend not just on total dose but also dose rate, radiation type, and tissue sensitivity.
