PERSONS INVOLVED
CMMP permitted workers - on authorised users list
PROCEDURE(S) COVERED BY THIS ASSESSMENT
Use of X-ray diffractometers in F10E. Sets are serviced annually by Panalytical and Rigaku
Could an alternative technique be used which involves less or no radiation?
NO
Could a lower energy exposure be used?
NO
Will any aspect of the work be carried out in a Controlled Area?
NO
room no
If YES please give details including equipment, energy, current-time product, radiation output per unit current-time
product at a specified distance, procedures:
Make an assessment of the risks:
LOW
The assessment of risks to personnel arising from ionising radiations should be based on the potential for dose
before controls are put in place.
This section may be used to explain the nature of the risks:
X-ray generators are used to perform X-ray diffraction
Will any aspect of the work be carried out in a Supervised Area?
YES
room no F10
If YES please give details including, equipment, energy, current-time product, radiation output per unit current-time
product at a specified distance, procedures:
Panalytical XPert and Rigaku Smartlab operating at up to 50kV
Make an assessment of the risks arising from the work:
This section may be used to explain the nature of the risk:
YES
Low Risk: X-ray generators are used to perform X-ray diffraction experiments
CONTROL MEASURES
Consider, in turn, each component of the radiation work and the Controls applicable to it, ticking any
relevant Control box. Where necessary please indicate other measures you have implemented to control
the risks arising from the work, in the space provided. The higher the risk the more stringent the Control
measure.
COMPLIANCE
to ensure adequate equipment and facilities
the College Co-ordinator for Ionising Radiations (ext. 46655) has been notified of this X-ray equipment by
the department/unit
the equipment meets the requirements of regs 31 & 32 IRR 1999
the equipment complies with the conditions of the generic authorisation
the equipment has an identification number or distinguishing mark
the supplier is reputable, e.g. has a quality standard
other control:
Annual Service by Panalytical and Rigaku
THE ROOM OR ENCLOSURE
as a means of minimising dose from unintended exposure the following are
implemented:
the room / enclosure is adequately shielded
the room / enclosure access is fitted with an interlock
an emergency stop button is provided and clearly positioned within the room
the entrance to the room / enclosure is fitted with a warning sign
other control:
X-ray equipment

LR24A
THE EQUIPMENT
indicate which of the following will be used to minimise exposure:
the equipment is operated by a trapped key system – to prevent accidental emission
the equipment is fitted with a means of locking off - to prevent uncontrolled use
the equipment is fitted with a safety device e.g. interlock, which will ensure that an exposure;
a) cannot commence whilst any access door is open
b) is interrupted if the access door is opened
c) does not recommence merely on closing the access door
the equipment is checked for radiation safety at least every 12 months, and always after repair or
modification, by a competent person
other control:
PERSONNEL
with regard to the people who may come into contact with the closed source:
those undertaking the work are authorised radiation workers
those undertaking the work are sufficiently trained
the work poses no risk to those who may be/are pregnant
maintenance workers and cleaners enter the room under ‘permit - to - work’
the work poses no risk to non radiation workers or other members of the public
other control:
We keep a list of designated workers
WORK AREA
to minimise exposure to non radiation workers, the work area will make use of:
delineated area / segregated from other work
fixed or mobile shielding
interlocks to prevent access to source room whilst X-rays are being emitted
other control:
Combination entry to F10E - only CMMP permit holders
MONITORING AND
PERSONAL DOSIMETRY as a means of detecting exposure the following are used:
film badges
TLDs
stray radiation is monitored annually by Panalytical
other control:
DISPOSAL
indicate which of the following disposal routes will be used
via the UCL Cleaning & Waste Service
via an Authorised Contractor
state contact details Panalytical, Rigaku
other control:
X-ray equipment

LR24A
DECLARATION
I the undersigned have assessed the activity and the associated risks and (delete as applicable) declare that
there is no significant risk/the risk will be controlled by the method(s) listed above. Those participating in the
work have read the assessment. The work will be reassessed whenever there is significant change and at
least annually.
