Letter of Application

[guentchev@inrne.acad.bg (Tihomir Guentchev)]

Dear Madam/Sir,
My name is Tihomir Guentchev and I am member of a Radioanalytical Lab.
at the Institute for Nuclear Research and Nuclear Energy,
Sofia,Bulgaria. I have taken your address from Job-Hunt. My wife won
"green card"in a "lottery" within the Diversity Visa Programme and I
plan to go to the USA with my family, so I am looking for a job. In
order to get the immigrant visa I need a letter from an employer in
the USA So, I would be grateful for any information about available
positions or any kind of help. I would like to hear your opinion about
the possibilities. I have 3 years of experience in radiochemistry. I
am working on development of separation schemes, methods and
procedures using extraction, chromatography, precipitation and
electrochemical methods. During the last 3 years I worked on the
following projects: 1. Reactor vessel dosimetry, determination of
phosphorous and other impurities in the vessel's steel, NPP "Kozloduy"
2.  Environmental project on estimation of radioecological status of
polluted by uranium mining and milling industry sites. 3.  Preparation
and control of activated carbon radioiodine filters for NPP. 4.
Development of methodology for determination of pure alpha and
betaemitters in environmental samples, using mainly EIChrom materials
and solvent extraction. 5.  Development of decontamination procedures
for contaminated metals, mainly for NPP. 6. Development of procedures
for preparation of standard sources for calibration, mainly for
gamma-spectrometry.
 Looking forward to hearing from you, Tihomir Guentchev. 

Enclosed is my Resume.

Sincerely yours, Tihomir Guentchev

Development of procedures for separation of radionuclides from air,
soil, water, food and technological samples. Determination of radium,
plutonium and thorium nuclides, strontium-90, lead-210. Separation
techniques mainly based on solvent extraction, extraction
chromatography (including EIChroM materials), coprecipitation and
ionexchange methods. Reactor vessel dosimetry - activation detectors
for neutron fluence monitoring (iron, copper and niobium)
Determination of phosphorus (International and Russian standard
procedures), copper, nickel etc. (AAS-ICP) in steel of pressure vessel
of Unit one of Nuclear Power Plant "Kozloduy". Development of
procedures for preparation of standard calibration sources for
calibration of gamma spectrometers were prepared in different
geometries, densities and Zeff from point source to 200 l drum source.

radioiodine on active carbon filters. Development of decontamination
procedures for contaminated metals, for NPP. Development of procedure
for calibration of military radiometric field laboratory. IN VITRO
solubility experiments for determination of the dissolution rate of
the respirable fraction of an aerosol sample from the reactor hall of
NPP"Kozloduy".
