Introduction:

The application of risk matrix for ionizing radiation medicine allow identify in proactive way the weakness of the process’ step, which implies in the design of safety and quality improvement plan for this.

Method:

Risk matrix method applied for radiosynoviorthesis and the myelosupressor treatment with Phosphorus-32 of polycythemia vera. The Cuban code SECURE-MR-FMEA 3.0 is used.

Results:

It was eliminated the 17% of the high risk with additional measures, and the medium consequences for workers and public are 30% and 14%, respectively. The most important identified safety measures were the initial radiological monitoring from different nuclear medicine department areas; the project revision based on the applicable safety regulations; a survey of civil construction works and equipment assembly before work began; training of nuclear medicine doctors in related aspects of nuclear medicine treatments; existence of treatment protocols; the analysis of learned lessons from radiological incidents; the periodical radiological monitoring from different services areas and the emergency procedure for the cases of mistake in the radiopharmaceuticals administration. Human factor was the major cause in analyzed radiological events (88 %).

Conclusions:

These results facilitate taking decisions for the best performance of radiosynoviorthesis and the myelosupressor treatment with Phosphorus-32 of polycythemia vera in Cuba. It is recommended to elaborate the safety improvement plan from these and focussing in the radiopharmaceutical administration operations in both cases.
