How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded lessons and assigned technical tutor. No fixed timetables: students progress at their own pace within the intake, which makes it possible to combine with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MicroShield, MCNP, QAD-CGGP, advanced Excel, in free, academic or evaluation versions. The assignments are based on real procedures for calculating shielding thicknesses, verifying radiation levels and selecting shielding materials. Assessment is continuous per module plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain the interaction of photons and neutrons with matter.
Calculate shielding using attenuation methods and buildup factors.
Select shielding materials for gamma and neutron radiation.
Design radiotherapy bunker shielding according to NCRP 151.
Apply point-kernel and Monte Carlo codes.
Where this takes you
Requirements
- No prior degree required.
- Internet connection and a computer capable of running the programme's software.
- Sufficient level of Spanish to follow technical regulatory reading.
