This a resume of our general procedure manual, reproduced for physicians to know about all procedures that will be under their responsibility because they are legally, the responsible for the facility and its practices, as is establish in BSS and many other documents regarding medical practice. Here we only intent to introduce a general framework about medical cyclotrons so we will only mention some useful concepts and its application in a

Regarding to electrical aspects we must emphasize that failure interlock never must be deactivated, before the in charge expert check it out and solve the situation, only after he/she sign the log describing the solution, operation can continue. It is important to remember that ignoring this interlocks and alarms has conducted, many times, to major

Before turning on cyclotron for a production run, the following operation parameters must

STEP ONE: MORNING CHECK OUT BEFORE TURNING CYCLOTRON ON: (EXAMPLE)

*Rf cabinet OK*

*Operation* 3 +0.1 MPa (435 + 14 psi) *Transport* 0.5 +0.2 MPa (73 +29 psi)

*Electrical power on, stable and normal Control cabinet OK*

*Gas valves Production* Máx 0.5 MPa (73 psi)

*Vacumm* 7x10-7 mbar (7 x 10 -5 Pa)

• Patient waiting room= Controlled area

• Door interlocks during cyclotron is on

• In use production line rupture

accidents injuring personnel and patients.

*Water leakage NO Normal operative ventilation OK*

*Shielding closed OK Nobody in OK*

*Water conductivity* 5 μSiemens *Water cooling temperature 20+2 ºC*

**8.1.4.3 Possible emergencies**  • Coolling system failure

• Inside hot cell

• Vial rupture

• Outside

new facility.

be checked:

• Adverse reaction, contraindication, diabetic patients

On mechanical and performance settings it is important to become religious with the daily log for parameters to be safely establish before start working, to be sure of, what we want to obtain is what we really will obtain after cyclotron runs in the desire conditions
