List of symbols

ME = Medium level laboratory

CC = Counties of competence

(a) = multiplied by the number of counties of competence (number of sampling locations)

(b) = according to the guide issued in 2005

(c) = on the ash of samples accumulated quarterly

(d) = on the ash of samples accumulated over half a year

(e) = on the ash of samples accumulated yearly

(1) = for laboratories equipped with an air sampler of medium air volume flow (Hunter):

Sampling frequency:

October 1st - April 30th: 1 per week

May 1st - September 30th: 1 or 2 per two weeks

Sampling duration:

October 1st - April 30th: 2-7 days

May 1st - September 30th: 5-14 days

Activity measurement by gamma spectrometry with a semiconductor detector. Due to the long sampling duration it is not reasonable to measure the beta activity of such samples as the natural isotopes decay away during sampling. Therefore, it could not be compared to the beta activity of samples collected over one day.

Annual number of samples: min. 40

(2) = for laboratories equipped with an installed or portable air sampler of small air volume flow:

Sampling frequency: at least 1 per week

Sampling duration: maximum 24 hours

Activity measurement: gross beta activity

Annual number of samples: 52-365

(3) = dose rate measurements at one location for each laboratory equipped with a Berthold UMO dose rate meter:

height: 1 m

measurement duration: 30 min
