Absorption Formula:
| From: | To: |
Absorption is a dimensionless quantity that represents the fraction of radiation absorbed by a material. It is calculated as the ratio of absorbed dose to activity and indicates how effectively a material absorbs radiation energy.
The calculator uses the absorption formula:
Where:
Explanation: This formula calculates the efficiency of radiation absorption by comparing the actual absorbed energy to the radioactive activity present.
Details: Calculating absorption is crucial for radiation protection, medical physics, nuclear safety, and understanding how materials interact with ionizing radiation in various applications.
Tips: Enter absorbed dose in Gray (Gy) and activity in Becquerel (Bq). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What does absorption value indicate?
A: The absorption value indicates what fraction of the radioactive energy is actually absorbed by the material, with higher values indicating more efficient absorption.
Q2: What are typical absorption values?
A: Absorption values range from 0 to 1, where 0 means no absorption and 1 means complete absorption of the radiation energy.
Q3: How does absorption differ from attenuation?
A: Absorption specifically refers to energy retained by the material, while attenuation includes all processes that reduce radiation intensity including scattering.
Q4: What factors affect absorption?
A: Absorption depends on material density, atomic number, radiation energy, and the specific type of radiation (alpha, beta, gamma).
Q5: Why is absorption dimensionless?
A: Absorption is dimensionless because it represents a ratio of two physical quantities with the same fundamental units (energy per unit mass per unit time).
