6.1 The Radiography installation shall include an autonomous and exclusive system objected to ensure the safety in and around the building facility in the site. The radiation safety system will ensure prevention of any danger or injury to the health of personnel working at the site, to drivers, visitors or to the surroundings as a result of the radiation used at the installation.

6.2 The installations shall meet all the requirements concerning radiation safety which are in force in the state of Israel under any law, regulations, orders or procedures relating to setting up radiation installations, handling Radiation Devices, preventing environmental damage, environmental monitoring of personnel working with ionized radiation and the safety and health regulations for personnel working with ionized radiation.

6.3 The Bidder must submit an overall safety plan, including a survey of risks and a plan of the means and procedures designed to ensure the required level of safety prepared by the relevant Israeli authority. After its approval by all the authorized bodies in Israel and by the Customer, the safety plan will become the certified obligatory safety plan. The safety plan will include directions and a program to the constructor .The constructor will submit the plan to the bidder for approval.

6.4 The Client/system operator shall be entitled to demand any change or addition to the safety plan or the safety means if it should seem to him important and necessary for ensuring the prevention of health risks to personnel working at the installations, drivers, visitors or to the environment.

6.5 The complete implementation of all parts of the radiation safety plan will be an essential condition for operating the Radiography Installation for the purpose of performing the Acceptance Test.

6.6 The contractor shall be responsible for arranging all inspections required in Israel under the law in order to obtain all necessary approvals and permits required according to any law for setting up radiation installations, dealing with Radiation Devices, for operation and installation of radiation

6.7 Without prejudice to the general statement aforesaid and in addition to it, the safety measures will ensure the following:

6.8 The system will provide permanent radiation protection for everyone at all times.

6.9 Two types of zones shall be defined in the installation and in its surroundings:

6.9.1 Restricted area: zone exposed to radiation.

6.9.2 A zone protected from radiation.

6.10 The restricted area, a zone exposed to radiation will be limited to the Radiography tunnel.

6.11 The radiation - exposed zone will be shielded by permanent means (reinforced concrete wall, lead or other for the shielding doors), that will ensure the shielding of the exterior of the restricted area.

6.12 All areas, rooms, systems and installations required for the operation of the Radiography Installation, including Operators’ and Image analysis room, will be in the radiation - protected zone- fully protected where no additional precautions are necessary.

6.13 All openings and approaches to the zone exposed to radiation will be permanently closed and locked (apart from the doors of the Radiography tunnel which will open and close automatically during the inspection cycle).

6.14 All openings and approaches to the radiation zone will be safe-guarded by an Interlock System. The Interlock System will operate at all times even when the Radiography installation is not operating. When any aperture whatsoever is opened at any time, indications will appear in the– System Operator workstation. Radiography system activation will be enabled only after safety confirmation of the operator of the radiography installation.

6.15 CCTV

6.15.1 The radiation tunnel will be surveyed at all times by a CCTV system.

6.15.2 The CCTV will cover all the volume of the tunnel in a way that will enable identify a person in the tunnel.

6.15.4 It is possible to use split screen for several cameras. The size of each camera on a split screen will be at least 10".

6.16 DVR

6.16.1 All cameras will be connected to a DVR system that will save the data in FIFO for at least 1 week.

6.16.2 The DVR will have the capability to export data to a known format (MPEG, AVI, WMV etc.)

6.17 The proposal will include a detailed scheme of the tunnel with the cameras locations, angles of coverage and technical specification.

6.18 The final approval for the CCTV system will be during DDR.

6.19 Using hardware only, the Interlock System will prevent the operation of the Radiography System when any opening leading to the radiation - exposed zone is open. The system will immediately stop the operation of the radiation source when the said opening is opened during radiation source operation.

6.20 The x-ray safety system will insure safe access to the restricted area using, in addition to the CCTV system, the following elements:

6.20.1 Emergency stops

6.20.2 Emergency stop pull-cords 6.20.3 Sensors (for external doors) 6.20.4 Warning lights

6.20.5 Sirens

6.20.6 Door interlock (switch)

6.20.7 Beacons for X-ray measure, with automatic siren;

6.20.8 Service switch 6.20.9 Public Address

6.21 The above elements will be connected to Radiation Safety System Controller.

6.22 In addition the CCTV inside the tunnel will activate also as an interlock i.e.

if one of the CCTV cameras is fault no x-ray will be authorized.

6.23 The controller will gather all safety information and accordingly authorizes or not the functioning of the x-ray. Controller output will be graphically displayed at the following positions;

6.23.1 Operator workstation console

6.23.2 Shift supervisor (at the Radiography building)

6.24 The permitted dose of radiation in the protected zone will not exceed (half) 0.5 µSv/h (0.05 mr/h) at any point, at a distance of 10 cm from the installation. Maximum Dose Rate in Operators working area or in the environment will not exceed 0.5 µSv/h.

6.25 The measurement shall be taken during normal operation of the installation during x-ray irradiation of a full container by source operating at maximum capacity.

6.26 In all parts of the zone exposed to radiation, audio and visual warnings will be installed which will give warning of a radiation system on Stand By mode and/or of emission of radiation. The coverage level of these warnings will be 100%.

6.27 In all areas exposed to radiation, emergency cutouts will be installed.

These cutouts, operated by hardware alone, will immediately stop the emission of the radiation source.

6.28 In all areas exposed to radiation, an intercom system will be installed to enable contact with the operator of the Radiography installation.

6.29 All doors (apart from the external doors to the Radiography tunnel used by trucks) shall be equipped with special locks, each with only one key to open it. No “master” keys for these doors will be allowed on the installation.

6.30 The doors shall be opened from the outside only by this key. The doors may be opened from the inside by means of an emergency (panic) lock. It will not be possible to slam the door shut without the key.

6.31 Public Address System (PA)

6.31.1 The system will be equipped with a PA system that will be audible throughout the restricted zone and the surrounding area.
