Envirotect reports that it has continued to install its copper radiofrequency cages across the UK throughout the COVID-19 pandemic. As an integral part of RF cage installations the company carries out a minimum of two RF Tests, the first on completion of the RF cage and a second after the magnet delivery. Each test is carried out at three frequencies to the requirements of the scanner manufacturer.
Managing director Niven Smith said: “Our highly experienced test engineers will agree a suitable date with the customer for each test and we require a customer representative to be on site to witness each test result. An RF test report is completed by the engineer which is then signed and dated by the witness.
“A copy of the test report is included in the operation and maintenance manual that is sent to the customer for their records upon completion of the installation. Our test engineers take photographs of each test result for their own records, which are kept on file to avoid any doubt and offer reassurance to all concerned if and when questions are raised at a later date”.
All scanner suppliers have detailed requirements for the RF cage performance, and RF tests help to establish whether construction meets these standards. Envirotect says that on occasions a cage can be accidentally damaged during the finishing works as a number of trades are on site throughout the room refurbishment. Tests can assist with locating an issue, which could be something minor such as a rogue screw piercing the copper lining.
