X-Ray Transmission Equation:
From: | To: |
X-Ray transmission (T) represents the fraction of incident X-ray intensity that passes through a material. It follows the exponential attenuation law, where the intensity decreases exponentially with material thickness.
The calculator uses the X-ray transmission equation:
Where:
Explanation: The equation describes how X-rays are attenuated as they pass through matter, with higher attenuation coefficients or thicker materials resulting in lower transmission.
Details: Calculating X-ray transmission is essential for medical imaging, radiation shielding design, non-destructive testing, and materials science applications.
Tips: Enter the attenuation coefficient in 1/m and thickness in meters. Both values must be positive numbers.
Q1: What affects the attenuation coefficient?
A: The attenuation coefficient depends on the material composition, X-ray energy, and material density.
Q2: What does a transmission of 0.5 mean?
A: A transmission of 0.5 means 50% of the incident X-rays pass through the material, while 50% are absorbed or scattered.
Q3: How does thickness affect transmission?
A: Transmission decreases exponentially with increasing thickness - doubling the thickness squares the transmission.
Q4: What's the difference between attenuation and absorption?
A: Attenuation includes both absorption and scattering, while absorption refers specifically to energy transfer to the material.
Q5: Can this be used for other radiation types?
A: The same principle applies to gamma rays, but different equations may be needed for other radiation types.
