By Vladimir A. Elin, JSC “Intersoft
Eurasia”, Russia.
Vladimir A. Elin
Vladimir A. Elin graduated magna cum
laude with a B.S. in Technical Sciences
from the faculty of Instrumentation
with specialization in radio electronic
systems and devices at the Moscow State
Technical University
n.a. N.E. Bauman
(MSTU) in 1984.
In 1988, Vladimir
A. Elin decided to
give up scientific
research in favour
of business, and
he went on to
create the medical-
technology
company “Bioteks.”
1989-1991 he
worked as a
director of scientific
and technological
laboratory
“Infotech-Inter”,
and as a director
of the Russian-
German joint
venture “Shanse”.
In 1993, together with the partners
Vladimir A. Elin established the
company “BBB”.
In 1995, Vladimir A. Elin and his
partners set up a management company
- JSC Corporation “EMSTS” - (a
unified international system of bonded
warehouses).
In 2007, Vladimir A. Elin together with
Vladimir A. Afanasenko established
a new logistics holding company JSC
“Smart Logistic Group”.
DO-RA: universal
dosimeter in a cellular
phone
March 29th, 2011, in the process of
working on a column on a situation at
Fukushima nuclear power plant, an idea
was born. It might be a good idea to have
every person in the world own a mobile
dosimeter that will be built into a cellular
phone or a Smartphone. The idea might
have stayed on paper, but for a letter from
a nuclear engineer complementing me
after the column came
out. I revisited the
column and realized
that a dosimeter in a
cellular phone needs
to be produced.
I decided to
name the future
model Do-Ra (from
first letters of the
phrase dosimeter-
radiometer). The
future model was
prioritised on June
24th 2011 and after
a year and a half, a
patent was received
from the Intellectual
Property, Patentsand
Trademarks Federal
agency in Russia.
Patent applications
were also filed in the
US, Japan, China, European Union and
Ukraine.
A team of developers from the
RFNC- (Russian Federal Nuclear Center,
Russian research and development
institute for experimental physics) in
Sarov city lead by the Doctor of Science
Alexei Kibalko as well as a group of
professional programmers worked on this
project.
DO-RA
The Do-Ra device connects to a
Smartphone through an audio jack and
works in conjunction with a mobile
software DO-RA.Soft, easy to download
to any mobile device from the Internet.
After clicking on the Do-Ra icon, a
software program launches and the Do-
Ra device starts to function. Measuring
ionizing radiation takes place every 4
seconds and for 60 seconds the Do-Ra
device constantly checks the results for
accuracy. After 60 seconds, the results
with potential accuracy are displayed on
the Smartphone screen informing about
radioactivity level (dose rate) at the
location, of the studied object, food, etc.
The DO-RA.Classic can easily be
used as an individual emergency indicator
by the personal of nuclear power plants,
while the DO-RA.uni with its silicon
(Si) sensor is suitable for use as an
individual dosimeter and, of course, as
an individual emergency indicator of
ionizing radiation.
The DO-RA. Classic is designed to:
periodic or continuous 24-hour
•
recording and indicationof equivalent
dose of gamma-radiation (“DEP”) of
its holder;
periodic or continuous 24-hour
•
recording and indication of ambient
equivalent dose of gamma-radiation
(“DP”) of its holder;
measurement
of
period
of
•
accumulation ofDPgamma-radiation
of its holder;
digital transfer of the accumulated
•
and stored data in the memory of the
device thorough an audio channel
to the smartphone processor for
subsequent display or transmission
through a mobile service provider to
the center of the radiation situation
monitoring.
The DO-RA.Classic can be used
to assess the radiation environment and
alarm the user of any radiation risk (above
threshold), as well as to identify areas of
contamination or radioactive sources of
gamma radiation.
At present, the current configuration
of the DO-RA.Classic allows it to be used
as a detection device, not as a measuring
tool. For this reason, its readings cannot
be used in official reports.
To ensure accurate interpretation
of the results generated by the DO-RA.
Classic, users are recommended to
contact professional organizations.
The DO-RA.Classic is best operated
in the following conditions:
ambient air temperature from-20° C
•
to + 55°
С
;
relative air humidity up to 95% at
•
temperature of + 40°
С
.
The DO-RA software also allows
users to photograph the source of ionizing
radiation. This can be done using the
