No.	Identification of the document, describing the testing method	Characteristic or parameter tested	Description of test (type of test, test principle or technique)	Range of testing	Items tested (materials, products)
4.	ELME-DN-04 / ver. 06 (Mar. 2017) ** in-house method	Dose rate H*(10)	Measurements with portable survey instruments	Dose H*(10) 0,1 uSv/h – 1 Sv/h U(k=1) = 25%	ionizing radiation sources, working, living and natural environment
5.	ELME-DN-03 / ver. 04 (Oct. 2018)*** in-house method	Surface contamination Bq/cm² or s⁻¹	Direct measurement - beta emitters (Eβmax = > 150 keV) (C-14, P-32, Fe-59,  Co-60, SrY-90, I-131, Cs-137, Tl-204 etc.) - alpha emitters (U-238, Am-241 etc.)	MDA, minimum detectable activity - beta emitters (SrY-90) MDA ≥ 0,06 Bq/cm² - alpha emitters  (Am-241) MDA ≥ 0,03 Bq/cm²	ionizing radiation sources and other surfaces
6.	ELME-DN-23 / ver. 02 (Jul. 2020) in-house method	Average or time dependant activity concentraton of Radon-222	Continous measurements with active meters (devices)	Radon-222: 50 Bq/m³ – 50 kBq/m³	air in living or working environment

* Laboratory can implement minor modifications of the method as necessary (e.g. adaptation to the new version). Detailes on the actual state of the scope is maintained by the laboratory.

** The portable device RSS-112 for dose rate measurements was added to the procedure. The device is in use and in metrological surveillance for years. The uncertainty budget was reevaluated, final value remains the same. In October 2015 the contribution of secondary cosmic radiation was further analysed and evaluated. In June 2016 new dose-rate meter Fluke Victoreen 451P-DE-SI was purchased, the response was evaluated and it was included in the quality system.

*** Complete evaluation of calibration factors for measurement of surface contamination and harmonisation with the requirements of the ISO 7503-3:2016 standard was performed. New portable contamination monitors Berthold LB 124 and CoMo 170 were purchased and included into quality system.
