Shot Calc

Radiographic exposure planning, in your browser.

Superior Integrity Services built Shot Calc for radiographers and made it free to share. Use it on your phone or desktop, without an account.

What you can calculate

• Gamma exposure estimates with source activity, material, film and distance inputs.
• X-ray exposure estimates between points from your approved technique chart.
• Source decay, inverse-square adjustments and geometric unsharpness.

You can save source records in your browser and install the app for offline use after the first successful load. Saved records stay with that browser and device.

Use with your approved procedures

SIS Level III has reviewed the app and its reference data. Results are planning estimates for trained personnel. Verify inputs and results against the applicable procedure and technique chart. The app does not authorize an exposure, establish a surveyed radiation boundary or replace your RSO, survey instruments or independent timer.
