Convert fluence into dose with guided physics settings. See results instantly, then export and compare. Made for clean, fast, reliable classroom and lab calculations.
Use particle fluence or direct energy fluence. The result appears above this form after submission.
This chart visualizes how absorbed dose changes with the selected fluence input while keeping other settings fixed.
Where:
| Case | Mode | Fluence | Mean Energy | Coefficient (cm²/g) | Dose (mGy) |
|---|---|---|---|---|---|
| 1 | Particle | 1.50 × 108 particles/cm² | 0.662 MeV | 0.032 | 0.509 |
| 2 | Particle | 8.00 × 107 particles/cm² | 1.250 MeV | 0.030 | 0.481 |
| 3 | Particle | 2.50 × 109 particles/cm² | 0.140 MeV | 0.029 | 1.626 |
| 4 | Particle | 6.00 × 106 particles/cm² | 5.000 MeV | 0.038 | 0.183 |
Fluence describes how many particles cross a unit area. In some workflows, you may also use energy fluence, which represents energy crossing a unit area instead of particle count.
Fluence measures particles or energy passing through area, while dose measures energy absorbed per unit mass. Dose depends on both the incoming radiation and the absorbing material.
It links the incoming energy fluence to absorbed dose. Different materials and energies produce different coefficient values, so using a correct value is essential for meaningful estimates.
The displayed relation is most common for photon energy fluence to absorbed dose estimates. For other particles, detailed stopping-power and transport models may be more appropriate.
No. They are illustrative presets for quick testing. For design, research, calibration, or compliance work, use coefficient data that matches your actual material and radiation energy.
Choose the unit that matches your source data. Particle fluence mode uses particles per area. Energy fluence mode uses either MeV/cm² or J/m² for direct energy-based input.
The graph is generated from your current input values. It shows how dose would vary if fluence changes while coefficient and other relevant settings remain constant.
Use it as an educational or preliminary estimation tool. High-stakes applications should rely on validated protocols, traceable reference data, and qualified professional review.
