## What is Oslony RTG?

Osłony RTG calculates radiation shielding for industrial radiography and gammagraphy (NDT).

Pick an X-ray tube from the manufacturers' catalogue or a gamma source (Ir-192, Se-75, Co-60, Cs-137), enter the workload and the room geometry — the app follows the beam from the focal spot through every barrier and tells you how much lead (or concrete, steel, barite concrete) is needed to keep the other side safe.

• Shielding for primary, scattered and leakage radiation
• Audit of an existing room: walls, ceiling and floor, layered barriers
• Room measurement with the LiDAR scanner and an augmented-reality preview
• Exclusion, controlled and supervised zones on the floor plan
• Method per PN-86/J-80001, checked against DIN 54113-3
• Cloud projects — the same data on iPhone and in the browser (oslonyrtg.eu)
• 9 languages and country settings for Europe

The app is an engineering tool for non-destructive testing companies and requires an account with a licence key issued to your organisation. It is not a medical app and does not process any health data. Results support the shielding design; the final assessment is made by the facility manager with the radiation protection officer.

## Version history (last 2 releases)

### 3.1 — 2026-10-17

• 3D room model: rotate the room with your finger and see the beam and the verdict for every wall. • Apple Watch app: mark the tube position, walk away and see which zone you are in. The watch shows the calculated zone boundary — it does not measure radiation. • New materials: tungsten, lead glass, barite plaster, magnetite concrete. • Regulations of the selected country next to the zones; app language follows the phone. • Calculation and translation fixes.
