Demo · three prepared rooms
See how Osłony RTG calculates.
Three prepared rooms, computed by the same engine that runs in the app — with the plan, the split across barriers and the zone distances.
These are prepared examples, not a calculator — the inputs cannot be changed here. Your own room is calculated in the app.
Recommended Pb shielding thickness
7 mm
governed by: Pb public
Pb personnel5 mm
Pb public6.75 mm
No-entry zone36.7 m
Barriers OK0 / 6
Read from the standard's curves — the physical model did not raise the requirement.
What drives the thickness
Wall 1 (N)4.50 mm
Wall 2 (E)4.25 mm
Wall 3 (S)4.50 mm
Wall 4 (W)4.25 mm
Ceiling4.50 mm
Floorthickest9 mm
Zone ranges
no entry36.7 m
A75.8 m
B146.7 m
unrestricted263.6 m
Logarithmic axis — on a linear one the no-entry zone would vanish next to the unrestricted area.
