DOSIRAD Company / its products
DOSIRAD is a small independent company,
created in March 1993 to pursue the production and sales of the
"nuclear films" developed by Kodak-Pathé France, over 20 years
ago. Its director, Jean ANDRU*,
is the engineer who was in charge of these products, at
Kodak-Pathé.
* after a long time of work in radon world, Jean ANDRU retired and DOSIRAD bought by french firm CARSO - chemical laboratories holding -, has got a new team with Frédéric Sarradin & Flavien Boudet.
DOSIRAD is the world's exclusive supplier
for the following products. Films are sold directly from
France, while radon products (KODALPHA and DOSIFILM) are
mainly sold through local distributors. Example in India, the only country where we have an
exclusive film distributor.
1- 
Special nuclear films, based on Kodak technology, for recording ionising particles
(alpha, proton, heavy ions, etc.) and neutrons.
One
such film, the LR115, is still used by numerous researchers,
around the world, for more than 20 years. DOSIRAD sells these films,
directly from France. Our "Export
Price List", in EURO, is
valid worldwide. It gives the list of the available films,
their formats (sheets or rolls) as well as their prices and sales
conditions. The background of the welcome page shows the LR115 film,
under microscope, after etching of the alpha tracks, in a soda
solution. Alpha tracks are clear holes while small scratches and dust
would appear black. So, when everything is well done, the counting
results are very accurate, despite of rather simple counting
softwares.
2 - 
A
small passive radon dosimeter, called KODALPHA (also called DOSALPHA).
It
has the size of a credit card and is especially design for natural
radioactivity measurements and detection of all kinds of buildings at
radon risk. Since 1987, the French IRSN had used them for the French
radon map. For more information, instruction sheet and prices,
please click on dosimeters.
Developed
by Kodak-Pathé, these dosimeters are based on the use of our
LR115 film, associated with our high-tech, industrial analysis
laboratory. These small dosimeters are so easy to ship, that they are
the only ones, which can be used all over the world and yet still be
analysed by our dedicated French laboratory. They are recognised and
approved in several countries, for more than 10
years. For instance, have a look to the results of the validation
tests in England, every 6 months, over the 13 last years.
If needed, ask us for the professional Price
List of the KODALPHA and DOSIFILM.
We
also accept some direct purchase orders of KODALPHA detectors from
non-professionals and from any countries. Then the French
prices of the KODALPHA detectors are applied. But, the
cost of the freight is added to these French prices. Up to 10,
the KODALPHA detectors are simply sent into large envelopes. Under
regular envelopes, it costs almost nothing to return the films to our
analyses laboratory.
3- 
Pillboxes
of numbered films, called DOSIFILM.
These
films are exclusively sold to radon professionals, in
pillboxes of 100 films. Like for the above KODALPHA, all the films analyses are included in their prices.
Please, have a look to the main principle
of use of these pillboxes of DOSIFILM films. But, these films can
be used in several ways. Please, have also a look to the pictures of
these different uses, on the DOSIFILM
page (not yet in English, sorry !).
Please,
contact
us to get the whole professional
price list of DOSIFILM and KODALPHA.
To
keep all the advantages of this new radon testing approach, all
the cups (opened or closed types) have to be re-used.
Only the films are sent back to our analysis lab. Then,
the DOSIFILM allows making radon measurements for the
cheapest prices of the market.
These
DOSIFILM films can be used as well as "open" or "closed" radon
detectors. They have only to be used in the following "open" or
"closed" cases :
1- "Open" detectors :
DOSIRAD
proposes a very simple "open case". Each DOSIFILM film is
inserted into a re-usable KODALPHA lid, just before starting the
radon measurement. Then, the lids are simply stuck to any surface, by
a double-side adhesive tape. This allows discreet radon measures (ex.
under tables, etc.) for the best price of the market.
This discreet way of doing avoids the lost or degradation of
dosimeters. Only the films have to be sent back to our lab for films
analyses, in regular envelopes. From which, an overall very low cost.
2- "Closed" detectors : (some pictures
of the following closed detectors are available on the French part of
this web site).
DOSIRAD proposes also alternative closed
detectors, to be used with the DOSIFILM pills of films.
2-1-
The first one is a large "calibrated goblet". A DOSIFILM film is
inserted into a KODALPHA lid (as above), but this lid is stuck inside a
calibrated goblet. This has been developed to get the very
precise "closed measures" that are needed for "EF"
assessments. Ask us about this "EF" method. It is based on
two simultaneous measurements, one opened and one closed. Since the
opened ones measure "radon + progenies" and the closed ones measure
only radon, the difference between both gives the progenies, that is
"EF". In 2003, such "goblets" had successfully passed 5
international blind tests, in USA, Israel, Germany,
Switzerland and the European Intercomparison of the NRPB.
Calibrations curves are available on request : EF versus the ratio "open measure" / "closed
measure".
2-2-
The second case is a small glass vial. A DOSIFILM film is
introduced in a re-usable glass-vial, just before use. The film is
removed at the end of exposure. This very new approach
has been especially developed for countries were only closed
detectors are allowed by the legislation. The glass vial's look is
very new in the motionless radon world. But, they give excellent
results and are now approved in Switzerland and Israel. As already
said, only the films have to be sent back for analysis. Like for the
above uses of the DOSIFILM, the "glass vials" are more designed
for the professionals who place themselves their
detectors. The "glass vial" method leads to a lot of
practical advantages, including a very low cost. Some pictures
of the "glass
vials" and "goblets" are available on the French part of
this web site.
2-3-
The third case is a "foldable" cubic case, called RADBOX.
After several blind tests, it is now approved and used in
Switzerland. It is the only closed radon detector of the market, able
to be sent in small envelopes ! Again, a picture is
available on the French pages of this web site. Please, ask us for
details.
2-4-
The last one but not the least ! Due to recent collaboration with
ALGADE french firm, DOSIRAD can also propose closed radon
measurement with DPR2 ALGADE Shape, with a last 2010 successful
test in PTB radon Chamber. Picture and other data are
available on www.algade.com. Please, ask
us for details.
The
DOSIFILM can also be used in "personalised" cases,
imagined by our customers, with our help. Two personalised "open
cases" are already used, in England and Italy. On the other hand, we
are able to use the DOSIFILM films in any kind of traditional or
experimental closed cases. A very successful Intercomparison has been
done in the so-called "Karlsruhe cases". Regarding the films
analyses, all the open cases have the same calibration factor, while
each "closed case" has its own calibration factor. Please, ask
us.
General information :
According to our knowledge, a single measure with our
"opened" KODALPHA gives the best overall assessment of the health
risk. It is simply because the health risk comes from the
progenies and not from the gas, while the closed detectors take only
care of the gas. More that 95% of the time, a closed and an open
detectors give exactly the same result, because "EF" is closed to
0.40 (as supposed by the legislation) and there is no thoron. But,
under certain circumstances, a closed detector can
underestimate the risk by a factor 2. After a general risk
detection in a building, with a KODALPHA, the complementary measures,
of any kinds, ought to be in charge of discovering the precise causes
of this health risk (radon, equilibrium Factor, thoron, etc.).
For general information about "radon gas", "natural health
risks", "radon measurements", etc. please click on info radon. This
provides a short extract from an excellent WHO (World
Health Organisation) information pamphlet, about radon.
To buy these pamphlets, please, have a look to the WHO site, at the WHO address. On the web, the research motors
would also give you many, too many, information. Take care to chose
the best key words ! We
suggest : LR115 film, radon
dosimeters, KODALPHA, thoron, equilibrium factor, radon progenies,
&, and all good web sites of the administration, &
Business : since only our
laboratory is in charge of all the films analyses, any of our
customers can easily start a radon business, with good prices,
without accreditation problems and without local investment.
By the way, we are still looking for new KODALPHA
distributors and professional's users of KODALPHA and DOSIFILM all
over the world.
