LESSON LEARNED FROM THE EUROPEAN ATLAS OF NATURAL
The conference will be held in the beautiful city of
Prague, capital of the Czech Republic, at the conference hall of the Masarykova
College, the Czech
Technical University (the same as
in 2006 and 2018). The Masarykova
College is located in the western part of central Prague, near the Prague
Castle, the dominant symbol of Prague, in the direction to the Ruzyne airport,
close by to the Dejvicka underground station (line A). It is also well served
by tram and buses. The best way to reach the venue from the airport is to use
the bus No. 119 (it has a stop at terminal 1 and 2 as well), which goes from
the airport to the Veleslavin underground station and then use the underground
line A (two stations) to the mentioned Dejvicka underground station.
Thakurova street No.1, 160 41 Prague 6
On site accommodation (i.e.
directly at the Masarykova College, medium/low price) is possible but limited
You can try to book via e-mail: firstname.lastname@example.org or via
The direct neighbourhood has also a
large number of excellent hotels, pensions, hostels, which you can find via
internet (we recommend to concentrate on accommodation in the central parts of
Prague – Prague 1 and/or Prague 6).
RIM - GENERAL INFORMATION
your radon measurement with the international community in friendly field environment -
comparison measurement of radon in soil gas at radon reference sites in the Czech Republic
comparison measurement at reference sites in the Czech
Republic, RIM 2021, will be organized as an independent part of the
International Workshop on the Geological Aspects of Radon Risk Mapping on
September 20th, 2021. Comparison measurements at
reference sites serve for verification of field radon measurements performed by
measurement will be organized at two reference sites Cetyne
and Buk established in 2000, located 60 km SW of Prague near the city Milín in
the Czech Republic. Both reference sites are accessible for cars. Radon
reference sites are situated on meadows, their soil cover enables soil gas
sampling at the depth of 0.8 m, and their mutual total distance is 12 km. Each
reference site implies 10 stabilized stations, which are marked by numbers. Single reference
sites differ in radon activity concentration in soil gas, the radon
distribution within the reference site is relatively homogeneous.
comparison measurements at reference sites are organized
for single participants or groups of participants. Results of tests will
be anonymous, each participant (group) will be denoted by a code.
Note: the fee for the
intercomparison measurement depends on the number of resultant sets of radon
data from single equipment for testing and on the number of participants in one
measuring group (more detailed info in REGISTRATION FEE and INSTRUCTIONS for
RIM we would like to focus not only on comparison of resulting soil-gas radon
concentrations, but on the sampling methods themselves.
participation in radon comparison measurement are:
- Radon comparison with
international expert community.
- Radon comparison with radon site
databases derived using measurements of 288 successful Czech
- The use of two well documented
radon reference sites fulfilling geological requirements.
- Based on more than 25-year
experience in periodical radon comparison measurement 1992-1999, and
- Three tests by computer programme
TestMOAR based on statistics, compiled by the Institute of Applied
Mathematics and Computer Technique, Faculty of Science, Charles University
for the comparison measurement: Instruction (via e-mail), transport from Prague
(provided on request, we recommend to arrange the transport to the reference
sites on an individual basis), meeting at the reference area, measurement of
radon in soil gas, reporting of resultant data (kBq/m3) from
measured stations and reporting results by 2 weeks after RIM measurement by
e-mail. Data processing and evaluation by TestMOAR will follow after all
participants provide the data. For those who will collect a lower number of
measurements at reference sites, programme TestMOAR accepts their number of
There is no
electrical power supply at radon reference sites, however a power supply
generator can be provided on the request. We expect we will meet with all
participants in the field in the morning, but transport from Prague can be
provided as well.
Accommodation: Please, take into consideration, that
this year “only” one-day intercomparison is hold. Suitable
accommodation, just in the area of radon reference sites, is available in
“Hotel u Milina” (www.hotelumilina.cz).

CALIBRATION OF RADON IN SOIL GAS DEVICES
of calibration of radon in soil gas devices in Calibration laboratory SUJCHBO,
v.v.i. – the accredited Calibration protocol
Laboratory SUJCHBO, v.v.i.: National Institute
for Nuclear, Chemical and Biological Protection (SUJCHBO, v.v.i.) is
certificated by Lloyd´s Register Quality Assurance according to standards ČSN
EN ISO 9001 - quality management system, ČSN EN ISO 14001 - environmental
management system, ČSN ISO 45001:2018 - safety management system.
Metrological Centre (AMC) working under SUJCHBO v.v.i. ensures the metrological
traceability for devices measuring the radon air concentration and the energy
equivalent radon concentration connected with the radon decay products (RnDP).
The AMS laboratory is authorized by the UNMZ (Czech office for standards,
metrology and testing). Calibration Laboratory is accredited by the Czech Institute
for Accreditation according to the standard ČSN EN/IEC 17025:2018 and
certificated by Lloyd´s. Following the metrological traceability, the AMC is on
the same metrological level as BfS Berlin. These two institutions compare
results periodically and cooperate in some international research
plan for calibration: Expected time
schedule differs for continual radon monitors and for grab sampling devices.
In case of continual monitors, a responsible person from SUJCHBO will pick up the
participant´s continual monitors at reference site Buk on Monday, September 20th,
2021, after the RIM intercomparison comparison measurement. It is necessary to
prepare some similar operation manual and pack it for transport together with
owner´s contact data. Devices will be exposed in the Radon-aerosol chamber of
SUJCHBO under two different levels of radon activity concentration. On
Thursday, calibration of continual radon monitors will be completed and the
responsible person from SUJCHBO will transport participant´s devices back to
Prague (GARRM venue). Participant will download data from the device and send
results from two expositions no later than one month after the calibration.
Time of each exposition will be sent to participants briefly after the calibration
process. Based on the participant´s results, SUJCHBO will send the accredited
Calibration protocol to each participant forthwith.
sampling radon in soil gas devices – on Friday, September,
24th, at about 8,00 in the morning; we will organize the transport
of interested persons + equipment from Prague to the Calibration laboratory of
SUJCHBO, Kamenna. Participants will take samples of the air from
prepared sampling rubber tires with three different levels of radon activity
concentration. Because of limited volume of air in the sampling rubber tires,
participants can take at most four 150 ml samples (600 ml together) from each
level of radon activity concentration. Expected time of arrival back to Prague: Friday, September 24th at about 14,00
– 15,00 in the afternoon. Participants will send the results of three
levels of radon activity concentration no later than one month after the
calibration. Based on the participant´s results, SUJCHBO will send the accredited
Calibration protocol to each participant forthwith.
Limits of participants/devices number – due to the
time schedule and due to the special price for calibration as well, there are
limits of participants/devices for the calibration:
continual monitors: 5 – 15 devices
grab sampling devices: 5 – 15 devices
So, please take into account, that the number of participants
WORKSHOP FIELD EXCURSION
Workshop field excursion will be organized on
Friday at the end of the workshop (an optional activity with a special fee).
Expected time of departure – Friday,
September, 24th, at about 8,30 in the morning; expected time of
arrival to Prague - Friday, September 24th
at about 17,00 – 18,00 in the evening.
