Safety instructions
Designated use The FQG61 and FQG62 source containers described in this document contain the radioactive source,
which is used for radiometric measurement of level, interface and density. They screen the radiation
from the surrounding environment and allow it to be emitted almost unattenuated in the direction of
measurement only. In order to guarantee the screening effect and rule out damage to the radiation
source, it is essential to comply strictly with all the instructions provided in this Technical
Information document for mounting and operating the unit, as well as all legal regulations
surrounding radiation protection. Endress+Hauser does not accept any responsibility for damage
caused by incorrect use.
Basic instructions for use and
storage
• Observe the applicable regulations and national/international standards.
• Comply with radiation protection regulations when using, storing and working with the
radiometric measuring system.
• Heed warning signs and observe safety zones.
• Install and operate the device according to the instructions in this document and as specified by
the regulatory authority.
• Never operate or store the device outside the specified parameters.
• When operating and storing the device, protect it against extreme influences (i.e. chemical
products, weather, mechanical impacts, vibrations etc.).
• Always secure the OFF position of the source insert using the padlock
• Before switching on the radiation, make sure that no-one is in the radiation zone (or inside the
product vessel). The radiation may only be switched ON by properly instructed staff.
• Do not operate damaged or corroded devices. Notify the competent radiation safety officer as soon
as damage or corrosion occurs, and follow his/her instructions.
• Conduct the required leak testing procedure according to the applicable regulations and
instructions
LWARNING
Vibrations and mechanical impacts
‣If the device is exposed to strong vibrations or mechanical impacts, the safety pin can become
abraded. This may cause the source insert to fall out of the container.
‣Therefore, the source holder must be checked at regular intervals to ensure that it is secure and
stable
LCAUTION
Condition of the system
‣If there are any doubts about the proper condition of the system, check the area around the
device for leakage radiation and notify the competent radiation safety officer.
Hazardous areas General instructions
LCAUTION
Suitability
‣The suitability of the radiometric measurement method and of the device for applications in
hazardous areas must be checked by the plant operator according to the national rules and
regulations that apply.
The following must be observed:
• Avoid electrostatic charge at the device. Do not rub dry.
• The device must be integrated in the potential equalization system of the plant. In order to ensure
electrical contact between the radiation source container and the mounting support, the supplied
toothed lock washers must be used.→  37
If an RFID tag is used, comply with the instructions in the
SD01502F/00 document, which is supplied separately

Additional instructions for pneumatically operated radiation source containers
LCAUTION
Hazardous areas
‣For applications in hazardous areas categorized as ATEX II 2 G, the associated Safety Instructions
(XA) must be observed.
‣The pneumatic drive may not be operated in locations where the ambient conditions may lead to
corrosion in or at the pneumatic drive.
General instructions on
radiation protection
When working with radioactive sources, avoid any unnecessary exposure to radiation. All
unavoidable radiation exposure must be kept to a minimum. Three basic concepts apply to achieve
this:
ABC
A0016373
A Screening
B Time
C Distance
Screening
Ensure the best possible screening between the radiation source and yourself and all other persons.
Source containers (e.g. FQG60, FQG61/FQG62, FQG63, FQG66) and all high-density materials (lead,
iron, concrete etc.) can be used for effective screening purposes.
Time
The time spent in the exposed area should be kept to a minimum.
Distance
Keep as far away from the radiation source as possible. The local radiation dose rate decreases in
proportion to the square of the distance from the radiation source.
Legal regulations for
radiation protection
The handling of radioactive emitters is legally controlled. The radiation protection regulations of the
country in which the plant is operated are of overriding importance and must be strictly observed. In
the Federal Republic of Germany, the current version of the Radiation Protection Ordinance applies.
The following points derived from this Ordinance are particularly important for radiometric
measurement:
Handling permit
A handling permit is required for operating a plant which uses gamma radiation. Permit applications
are made to the local state government or the authority responsible (State Offices for Environmental
Protection, Trade Inspection Offices, etc.). The Endress+Hauser sales organization will be happy to
help you obtain the handling permit.
Radiation safety officer
The plant operator must appoint a radiation safety officer (RSO) who has the necessary specialist
knowledge and who is responsible for observing the Radiation Protection Ordinance and all radiation
protection procedures. Endress+Hauser offers training courses in which individuals can acquire the
necessary specialist knowledge.

Source container FQG61, FQG62
10 Endress+Hauser
Control zone
Only persons who are exposed to radiation during the course of their job and are subject to official
personal dose monitoring procedures may work in control zones (i.e. areas where the local dose rate
exceeds a specific value). The limit values for the control zone are specified in the current Radiation
Protection Ordinance applicable for your area. The Endress+Hauser sales organization will be
pleased to provide further information on radiation protection and regulations in other countries.
Supplementary safety
instructions
Observe the associated safety instructions contained in the following documents:
SD00292F/00 (for Canada)
SD00293F/00 (for the United States)
This document, together with the nameplates, constitutes the documentation for highly
radioactive radiation sources as stipulated in Section 94 (3) of the Radiation Protection
Ordinance in Germany.
LCAUTION
This device contains more than 0.1% lead with CAS No. 7439-92-1.
‣The lead is not accessible in vessels that are free from damage. If the vessel is damaged, national
regulations surrounding the handling of lead must be observed.

Function and system design
Function Function of the radiation source container
In the FQG61/FQG62 source container, the radioactive source is surrounded by a steel casing filled
with lead which screens off gamma radiation. The radiation can be emitted, almost unattenuated, in
one direction only through a channel (focused narrow beam path). This radiation is used for
radiometric measurement.
Switching the radiation ON and OFF
• By turning the insert 180°, the radiation source is positioned in the radiation emission channel
(radiation is switched on) and removed from the channel (radiation is switched off).
• The current switch position (ON or OFF) is clearly visible from the outside.
• The OFF position can be secured by a cylinder lock or padlock (depending on the version; see
product structure: order code 020, "Version").
• The ON position can be secured by a cylinder lock, a padlock or a locking bolt (depending on the
version; see product structure: order code 020, "Version").
Remote control/remote indication of the switch state
Device versions with a pneumatic drive are available, which enable the radiation to be switched on
and off remotely (product structure: order code 020, "Version K, L, M, N"). These versions have
proximity switches for remote indication of the switch state (ON or OFF).
Fire-resistant version
A fire-resistant version of the radiation source containers is available (product structure: order code
670 "Additional function"). This version has a compensation compartment, which is welded onto the
housing. In the event of a fire, the liquefied lead is collected in the compensation compartment, thus
ensuring the enhanced fire-resistance of the source container.
