NORM/LSARadioactive substances occur at most

oshore locations. Natural Occurring

Radioactive Material (NORM) or Low

Specic Activity (LSA) are the collective

names or these naturally occurring

radioactive substances which may be

released during the production o oil and

natural gas. Traces o these substances

have been present in the ormations rom

which oil and natural gas are extracted

ever since the earth was ormed. During

the production process they can be

brought along to the surace, either as

gas or as salts (dissolved in water or

in a solid state). It is thereore possible

to nd gaseous radioactivity in the

orm o radon gas in the production

environment. The radioactive substances

can accumulate (in sludge) in some

installation components or orm

accretions (scale) inside pipes, tanks and

vessels.

What are the characteristicsof NORM/LSA? Invisible and odourless.

Measurable using special equipment.

Health hazard.

Environmental hazard.

Where, when and how canyou come into contact withNORM/LSA? When a closed system or installation

leaks liquids and/or gases.

When a closed system or installation

is opened.

Gsus: radon

liquid fm: (watery) sludges

Sid fm: scale

Radiation risksThe radiation dose you are likely to

receive due to NORM/LSA is low and

not harmful. However, radiation caused

by NORM/LSA can pose a health risk in

cases o:

Regular and long-term exposure to

relatively small doses o radiation.

Direct internal contact with

NORM/LSA.

Preparations for the jobBeore you start work, the Radiation

Expert will explain the risks involved.

contamination measurements at the

workplace.

measures are observed during the job.

Provides advice on how to

prevent radiation leaks, spills and

contamination.

suraces to be treated are kept wet.

Store and dispose o NORM/LSA-

contaminated components in

accordance with the applicable

instructions.

What personal protective

equipment? Basic PPEs

Non-porous gloves

Disposable overalls and rubber safety

boots

If dust is produced: full-face masks

with independent breathing protection

During welding (evaporation product):

pressurised welding mask with

Personal hygiene Wash your hands before eating,

drinking, smoking or using the toilet.

Beware of contamination of your PPEs

or NORM/LSA contamination.

Contamination withNORM/LSAExternal: on the skin through contact

with sludges (rom bottoms o tanks

and vessels) and scale (on the insides

o piping).

Internal: as a result o inhaling dust

between fanges, dust particles released

during maintenance work or as a result o

evaporation during welding.

Internal: as a result o swallowing

splashes o sludge or due to eating ood

contaminated by hands.

What to do in case ofcontact, inhalation orswallowing?

Always warn the Radiation Expert

immediately.

external contact

Wash the contaminated areas

thoroughly. In most cases, no

contamination will be measured ater this

has been done.

Internal contact

Some substances are excreted by

the body; others are not. Any orm

o inhalation or swallowing must be

avoided. I it nevertheless happens,

ollow the relevant work instructions

and immediately notiy the Responsible

Radiation Expert (RRE).
