Per meter to half-value layer (cm)
Type a value in m⁻¹ to get it in HVL cm instantly.
6.08HVL cm
That's about the same as concrete (Co-60). Cutting the beam a thousandfold takes about 60.59 cm of it.
What it means
How strong a shield is that?
Narrow-beam attenuation. Real shields let through more because of scattered radiation (build-up); design shielding to the relevant standards.
The math
How to convert m⁻¹ to HVL cm
HVL = ln 2 ÷ μ = 0.693 ÷ μ; TVL = ln 10 ÷ μ = 2.303 ÷ μ.
Example: 11.4 m⁻¹ = 6.08024 HVL cm.
