1. XR 3500/3700 Safety Information
IMPORTANT: READ THIS FIRST

It is essential that the operator of the XR 3500/3700 read and understand
the following safety warnings PRIOR to operation.

The XR 3500/3700 is designed to provide safe and efficient operation.
However, any equipment producing ionizing radiation (X-rays) must be
considered hazardous and should be treated accordingly. When
operating this equipment, observe the following:

 PACE strongly recommends that all maintenance be performed by

a qualified service technician.

 The XR 3700 x-ray tube produces high voltages of up to 70,000

volts. The XR 3500 X-ray tube produces high voltages of up to
50,000 volts. Under no circumstances should the case be
disassembled or modified as severe electrical shock may occur.

 The XR 3500/3700 is designed to ensure adequate radiation

shielding. Even so, always be aware that the ionizing radiation (x­rays) can constitute a distinct hazard if not employed in strict
accordance with instructions provided in this manual for maximum
operator safety.

 Exposure to excessive quantities of radiation can be dangerous to

your health. Avoid not only direct radiation exposure, but also to
secondary or scattered radiation which occurs when an x-ray beam
strikes or has passed through any material.

 Do not insert any part of the body into the inspection chamber while

x-rays are on. Although the XR 3500/3700 operates at a low x-ray
dose, unnecessary radiation exposure should be avoided. If an
item becomes jammed or lodged in the inspection area, the XR
3500/3700 should be turned off before any attempt is made to clear
the inspection chamber.

 PACE strongly recommends that all personnel operating the XR

3500/3700 wear a radiation film dosimeter badge. This badge
records an exposure history for the operator and acts as a constant
reminder to the operator to use caution and safe work practices
when operating the XR 3500/3700.

 The radiation exposure dosage received by personnel working with

x-ray inspection equipment should not exceed those limits set by
local regulations relating to ionizing radiation.

 Adequate warning signs and symbols should be displayed in the

vicinity of the XR 3500/3700 warning of possible x-ray exposure.
Any warning lamps and signals should be checked prior to
operating the XR 3500/3700.

 The electrical circuits of the XR 3500/3700, although enclosed for

operator protection, must be considered as a potential hazard.
Strict observance of safety practices pertaining to operation and
maintenance is essential. Proper electrical grounding must always
be used.

 Before operating the XR 3500/3700, all personnel designated or

authorized to operate the unit, as well as those supervising its
operation, should have a full understanding of how it works.
Additionally, they should be familiar with established radiation
safety exposure practices sanctioned by the National Bureau of
Standards Handbook, “X-ray Protection” HB93, pertaining to x-ray
protection.

 Service personnel should read this manual and be familiar with its

contents before attempting to adjust or repair this equipment.

2. Radiation Safety Information

Federal, State and Local Radiation Regulations (US ONLY)

This cabinet x-ray system was designed to conform to U.S. and Food
and Drug Administration (FDA) requirements as stated in the Code of
Federal Regulations, Title 21 (21CFR). These requirements (often
referred to as the CDRH or BRH regulations) govern the design and
manufacture of all equipment that produces ionizing radiation. Such
equipment includes television sets and microwave ovens, as well as
cabinet x-ray systems. In fact, the maximum allowable radiation
emission for cabinet x-ray systems is the same as that set for
television sets and microwave ovens.

Warning: Failure to adhere to the following warnings may

result in exposure to radiation:

 Do not operate the x-ray system unless all system components

and features are in good repair.

 Never attempt to remove any system component or bypass any

system function.

Several features are included in the system design to provide for
radiation safety. The controls (including key switches), control circuitry,
leaded components (including the leaded acrylic windows), physical
barriers, interlocks, and status and warning indicators each contribute to
overall radiation safety.

The Federal Aviation Administration (FAA), Occupational Safety and
Health Administration (OSHA), most state and some local government
agencies typically have specific standards regarding operational safety
and constraints regarding the modification of x-ray systems conforming
to 21CFR (mentioned above).

Typically, an x-ray system must be registered with the appropriate state
agency, by the physical possessor of the system, regardless of the legal
owner. Frequently, registration must occur prior to the x-ray system
being placed into service. Regulations may require initial and periodic
inspections by a government agency or a qualified vendor. In addition,
the regulations may require the implementation of standardized
operating procedures, specialized training, the distribution and use of
exposure monitoring badges and posting of radiation exposure
warnings and other special notices. Radiation safety requirements may
differ slightly from one jurisdiction to another. It is the user’s

responsibility to ensure that the x-ray system is installed and
operated in compliance with all applicable governmental
regulations. Failure to comply may result in substantial penalties.
