Elekta's investigation found that there is a potential risk where legionella bacteria may be present in the unity machine room, specifically the heat exchanger condensation collection tray.This risk is only significant to service users working directly on the condensation collection tray and immediate area.Clinical users and patients have no exposure to this potential hazard.Elekta has identified an area within the elekta unity system that has the potential environmental conditions for legionella bacteria to form.The area with this potential is the condensation collection system for the heat exchanger located within the unity machine room.The unity machine room has restricted access and shall only be accessed by trained personnel.In normal operation there is no risk of any users or patients being exposed to legionella bacteria should it be present.There has been no reported presence of legionella bacteria in elekta unity systems, this has been identified as a potential hazard only.The presence of legionella bacteria in the unity machine room does not impact the safe operation of the system nor does it pose any change to delivery of a treatment.There is no change in risk to the patient or clinical user.Only service users working directly on the area of potential legionella bacterial growth are at risk.
