– 7 – EN 61098:2007
7.3 Minimum detectable surface emission rate
Delete “Decision threshold” in the headline.
Replace “decision threshold” with “minimum detectable surface emission rate” wherever it
appears (also in any subclause).
Add new paragraph between the first and the second paragraphs, reading:
Since the minimum detectable surface emission rate depends on the response of the equipment
and this is going to depend on where on the body the activity is to be measured, the minimum
detectable surface emission rate is dependent on where the activity is. In order to provide some
indication of performance an average minimum detectable activity shall be determined from the
average efficiency. Since also the signal from the background can be large by comparison to
the signal from the activity being measured, and this background will be far from constant both
in terms of time and position, allowance in determining the minimum detectable surface
emission rate shall take account of this. The user also has a significant effect on the
background. In this document the minimum detectable surface emission rate has a special
meaning and includes arbitrary factors not used in the more precise decision threshold defined
in ISO 11929.
7.3.1 For clothing or body
Replace the first paragraph with:
For the purposes of this document, the minimum detectable surface emission rate shall relate to
the 4 π body average efficiency to clothing (body). This shall be determined as below, or the
manufacturer shall undertake similar methods of determining an average efficiency. In the latter
case the manufacturer shall provide the purchaser with a full description of the phantom used,
all measurements taken, the assumptions made in calculating the average efficiency and the
calculations made to determine this “average”. The 4 π efficiency shall be determined from both
the vertical response characteristic shown in Figure 1 and the polar response given in Figure 2.
Delete the third sentence of the third paragraph.
In the last paragraph, replace the second sentence with “Where monitoring is undertaken by
two or more steps, the sum of the times taken for each monitoring step shall not exceed the
time specified above or a time agreed between the manufacturer and purchaser.”
7.4 Variation of response with energy
7.4.1 Beta
7.4.1.1 Requirements
90 90 90
Replace “ Sr” with “ Sr/ Y”.
7.4.1.2 Method of test
Add in the second line of item b) “or by default 10 cm x 10 cm (performing two measurements
without overlap in order to cover the whole detector area and using the mean response for
further reference)” behind “15 cm x 10 cm”.
Add in the second line of item c) “or by default 10 cm x 10 cm (performing three measurements
without overlap in order to cover the whole detector area and using the mean response for
further reference)” behind “30 cm x 10 cm”.
7.4.3 Gamma
7.4.3.3 Method of test
Item a), first paragraph, second sentence: add “of the nuclide” between “A small source” and “of
interest”.
Item b), first paragraph, last word: replace “counter” with “detector”.
Add in the second line of item b) “or by default 10 cm x 10 cm (performing two measurements
without overlap in order to cover the whole detector area and using the mean response for
further reference)” behind “15 cm x 10 cm”.
