Transport of LSA waste to shore When transported to shore, LSA waste must be isolated to

the extent possible. This includes: o wrapping the equipment in plastic o protective caps mounted on valve and tubing ends o using primarily a closed container or secondarily if the

equipment is to big, a loading equipment. If a closed

container cant be used it is important that the equipment isproperly sealed.

Transport marking All transported LSA waste shall be marked in accordance with

ATTACHMENT 3:

MEASUREMENT OF-RADIATION

Application area Measurement of radiation is used for the measurement of:

components with LLW loose materials lead deposits The measurements can be carried out directly on the

component or on a sample taken from the component

Calibration of instruments1. Use the standards where the ratio between the nuclides 226Raand 228Ra is 3:1. These containers are labelled with yellow labels

on the lids.

2. Measure the background counting rate on site over a period ofa few seconds. If the background is significant (> 5 CPS), thenthe measured counting rate must be adjusted accordingly.

3. The lid is screwed off the container before calibration. Specificactivity of 226Ra + specific activity of 228Ra in units of Bq/g areindicated on the label on the bottom of the container. Note this.

4. Place the probe in direct contact with the surface of thedeposit and start measuring. It is recommended to measure theaverage counting rate over a period of few seconds.

5. Repeat this procedure for the two other standards in this series.

The result can be illustrated graphically by displaying the specificactivity in Bq/g as a function of the counting rate in CPS, asillustrated in the example below. A straight line is drawn in thebest possible way through the three measurement points. Ahorizontal line is then drawn in on the graph denoting the LLWlimit for classification as free, which will correspond to 13.3 Bq/g,since we measure the specific activity of the sum of the tworadium isotopes and the ratio between them is 3:1.

For the classification of 210Pb deposits, the line on10 Bq/g is used

as the criterion for classification as free.Counting rate - specific activity

Measurement directly on the component1. Before taking a measurement. Turn the instrument on first

and check the battery voltage.

2. Then check the counting rate against a known radiation source.One of the standards in the LLW standard set is suitable for

this purpose.

3. To prevent the measuring probe from getting dirty, it isadvisable to cover it with thin cling film.

4. Measure the background counting rate on site. If it is low(< 5 CPS) you can ignore it.

5. The measurement is performed by holding the measuringprobe in close proximity to the internal surface of thecomponent. Measurements should be taken at a numberof different points on the component. The measurementpoints should be chosen based on where it is most likelydeposits will be found.

6. The measurement result in CPS shall be entered in the

measurement report.

7. Specific activity in Bq/g can be determined based on theinstruments calibration curve. The value shall be entered inthe measurement report.

Measurement of deposit or loose material samples1. Extract a suitable amount of material (100-200g) from the

component and place it in a container similar to thecalibration containers.

2. Take the container to a site where there is no explosion riskand there are no other radiation sources nearby.

3. A functional check of the instrument shall be performedbefore taking a measurement. Turn the instrument on firstand check the battery voltage.

4. Then check the counting rate against a known radiationsource. One or the standards in the LLW standard set issuitable for this purpose.

5. To prevent the measuring probe from getting dirty, it isadvisable to cover it with thin cling film.

6. Measure the background counting rate on site. If it is low(< 5 CPS you can ignore it.

7. The measurement is performed by holding the measuringprobe in close proximity to the sample. Find the averagereading. The measurement result in CPS shall be entered inthe measuremen report.

8. Specific activity in Bq/g can be determined based on the

instruments calibration curve. The value shall be entered inthe measurement report.

ATTACHMENT 4:

MEASUREMENT OF -(GAMMA)RADIATION

Area of application The metering of -radiation on the exterior of pipes orcomponents is used when measurement directly on coatingor scale (see Appendix 5) is not possible, or when, for somereason, the presence of low level radioactive scale (LRA)is to be determined. One possible area of applicationcould be metering on the exterior of the separator tank fordetermination of deposits of LRA in the produced sand

The metering is to be conducted with gsensitiveinstruments, for example a dose meter. The unit displayedby the instrument is not important: the concluding result willbe obtained

Method limitations The method is qualitative, meaning that it only determines if

LRA is present or not The method has a high determination limit, meaning that itwill give a positive result only when large quantities of LRAare present

The method can not be used to demonstrate potentialdeposits of radioactive lead (210Pb)

The method is sensitive to other possible nearby deposits ofLRA

Metering procedures1. Clean the instrument before metering, to ensure that the

instrument is not contaminated from earlier measurements.

2. Test battery function.

3. Survey the background spectrum by metering the area

surrounding the pipe/component to be metered. This is doneto find possible other deposits of LRA that could affect themeasurement.

4. Measure the background spectrum about 30 cm from wherethe metering is to take place towards the area where thebackground spectrum (see point 3) is the strongest. Recordthe result as Background.

5. With the instrument in contact with the surface of the pipe orcomponent, commence metering. Record the result asMeasurement.

6. If Measurementis considered to be definitely larger thanBackground, the presence of LRA is proven. (Comment: it ispractically impossible to define more specific criteria than the

above. The correct use of the method depends on the usersexperience and good judgment.)
