3.2.3 RX EXPOSURE TIME

In the following tables the exposure times (s) associated to kV and mAs are reported. Since

the apparatus is a device functioning with a two point technique (kV and mAs) we remind that the

values indicated in the table are merely theoretical and can undergo a variation in relation to the

tolerance of the mA.

1 SAFETY

1.1 INTRODUCTION

The aim of this manual is to provide qualified radiology technicians, medical and paramedical

staff with operating instructions to make use of the radiographic unit simple and safe.

This apparatus emits X-

RAYS and must only be used in compliance with the safety instructions

indicated in this manual and must not be used for any other purposes than those foreseen.

The system must only be used by personnel with the necessary knowledge in the field of radiation

protection and with the necessary training in use of X-ray apparatus.

Follow the indications given below very carefully:

 the apparatus must not be used when there are any electrical and/or mechanical faults;

 do not use the system when any signalling or alarm device of the system is not working

properly;

 under no circumstances work with the unit

in places saturated with vapours and/or

flammable gases or explosives;

 any modification to the system must be authorised in writing by the

MANUFACTURER;

 if you want to use the apparatus in combination with other equipment, components or

modules, and when compatibility with the latter is not certain, it is indispensable to make

sure that there is no danger to the patients and/or operating personnel. In this case, consult

the manufacturer of the apparatus in question or an expert in the sector;

 like any other apparatus, the System must be used correctly. It also need

1.4.2 ELECTRICAL SAFETY

 Make sure that the power supply socket where the apparatus is to be connected is

approved for the foreseen voltage and current for use of the system

 the radiology system must not be used in rooms where there is the risk of explosion

SAFETY AND MAINTENANCE

1.5 PROTECTION AGAINST IONISING RADIATION

Before carrying out any X-ray exposure, make sure that all the necessary precautions against

radiation have been taken.

During radiation emission, the personnel in the X-ray room must respect the regulations in force

regarding protection against radiation. For this, bear in mind the following rules:

 where necessary, use protective accessories against radiation;

 always use the special X-ray protective coats: an X-ray protective material equivalent to

0.35 mm of lead (0.35 mm Pb) attenuates the radiation produced at 50 kV by 99.95%

and at 100 kV by 94.5%;

 the best protection against radiation is distance: therefore keep as far away as possible

both from the source of radiation and from the exposure object, also by using the suited

exposure-push-button with its extensible cable;

 avoid moving or standing in the path of the rays;

 always use the smallest exposure range possible: the radiation dispersed largely depends

on the volume of the object X-rayed;

 keep the patient’s examination area the furthest away as possible from X-ray source.

1.6 RESIDUAL RISKS

The system is designed and constructed according to the strictest principles of compliance with

safety requirements. However, there are residual risks due either to incorrect use of the apparatus

or to deficiencies in the protective measures taken.

With regard to the risks due to incorrect use of the apparatus, please see the instructions and

recommendations given in the points above and we

 The mobile unit has been designed and constructed so that it will not tilt over up to an

angle of 10° to horizontal in transport position (

advisable:

underline that:

SEE SECTION 3 - § 1). It is therefore

• not to stand, move or place the mobile unit on surfaces with a slope of more than 10°

• not to try to move the mobile unit with the brakes on

• to take care to avoid any obstacles on the floor when moving the mobile unit (cables,

steps and uneven levels of all kinds)

For the residual risks due to any defect in the protection measures taken, it must be remembered

that:

 Protection against electric shocks is carried out by means connecting the metallic

covering parts of the apparatus to earth: it is therefore necessary to periodically check –

according to the N

correct operation of the whole earthing circuit.

2.1 ROUTINE MAINTENANCE

2.1.1 GENERAL RACOMMENDATIONS

The radiological system requires regular checks and maintenance. The following

recommendations have the aim of helping the operator to keep the apparatus in good working and

safe conditions during service.

The system contains mechanical parts subject to wear according to use: following prolonged

use, wear on parts may decrease safety during use. For this reason, it is essential for the checking

and maintenance operations indicated below to be carried out consistently to protect the operators

and patients against any damage caused by mechanical breakdowns.

Correct adjustment of the electrical and electronic systems has a direct influence on the

operation of the system, on the quality of the image and on the electrical safety of the system, as

well as on the level of exposure to radiation the operators and patients are subjected to.

To disinfect the system, only use methods in compliance with the laws in force regarding

disinfection and protection procedures against explosion.

To carry out the cleaning and disinfection operations, take the following precautions:

 turn the system off and disconnect the mains power supply cable

 make sure that no liquid gets into the apparatus so as to avoid any short-circuits or

corrosion of the electrical and electromechanical parts.

The unit has not to be used in presence of anaesthetic and/or infiammable

disinfectant and cleaning products.

2.3 DISPOSAL OF DEVICE

During the disposal of a device you have to take case of the components that may present risks

connected to their elimination:

 the X-ray tube head holds an insulating dielectric means and lead protections that have

to be eliminated taking into account the standards and the laws in force (consult the

documentation released by the manufacture)

 the collimator holds leads shutters that have to be eliminated in respect of the standards

in force (consult the documentation released by the manufacture)

 the electrolytic capacitors holds an insulating dielectric means that have to be eliminated

taking into account the standards and the laws in force.

The other elements of the unit are composed of:

 ferrous material (chassis, screws, etc)

 plastic material (covering)

 electrical cables

 electronic boards.

These elements do not represent a direct source of risk during the elimination phasis of the devices.

The disposal of all components have to be carried out in compliance with the

!

local laws in force at the moment of the disposal.
