Radiocarbon dating principlesHow is C14 used for dating the past?14C (or Radiocarbon) is the radioactive isotope of the common element carbon. It is generally formed in the upper atmosphere by the interaction of cosmic rays with nitrogen gas (N2). The radiocarbon is oxidised to carbon dioxide (or CO2) and is instantantly mixed throughout the atmosphere. As carbon dioxide is used as the basis for photosynthesis, the radiocarbon is integrated into all living things. As far as plant or animal dies, the radiocarbon decays. It is known that half-life of radiocarbon is 5730 years. At radiocarbon dating laboratory could be measured the amount of remaining radiocarbon relative to the stable one which don’t change in concentration. Back-calculation to the time of death could be done using the known radiocarbon half-life. Radiocarbon content in the earth atmosphere is varying in time due to past changes in the strength of the earth’s magnetic field, the strength of the sun and changes in the carbon cycle. It cause that the one radiocarbon year does not equal one calendar year. Therefore radiocarbon age should be converted to calendar age using one of several available software packages Groningen, CALIB 4, OxCal, CalPal. Radiocarbon dating services & LabWelcome to the homepage of Radio carbon (14) dating services of Radioanalytical
lab of the Marzeev Institute of Hygiene and Medical Ecology located at Kiev, Ukraine.
02094, 50 Popudrenko, Kiev, Ukraine. 14C dating is performed in our lab using modern conventional (LSC based) method since 1993. For all LS measurements we use LS spectrometer Quantulus 1220TM, produced by PerkinElmer (formerly Wallac Oy). Teflon vials shaped 7 ml, 3 ml, 0,8 ml allow optimize LS counting performance for benzene samples of different mass. We have performed hundreds of carbon-14 analyses for our researches and some for commercial purposes. We would like to discuss a radiocarbon concerned projects and other radioisotope researches especially from early stage of planning. Please send your inquiry or any ideas to Dr. Michael Buzinny. Information on sample's submitted sizes required, you could find below. Our price corresponds to required time and precision, what kind of sample will be dated, corresponds to sample's size. Multi-sample discounts are offered for batches of submitted samples for conventional radiocarbon dating. Please send your inquiry to Dr. Michael Buzinny. How much material do I need for? and

Please inform us about your planes for carbon dating in our lab prior to sample submission. We have some additional advices for sample(s) submission and try to produce services in short period for your convenience.
All samples, to be analysed, should be clean, dry, bagged, and labeled Sample submission form & details, should be filled out printed, and posted with the sample(s). To help all users maximise the effectiveness of their carbon-14 analyses and to discuss sampling strategies and/or interpretation of any results we are pleased to any direct contact.
Pottery, ceramics & Radiocarbon (C-14) Dating (Novel)
Modern possibilities for carbon dating are now good tested for pottery and ceramic samples based on sufficient
amount of carbon required for analyses.
Carbon residues, sufficient amount of datable carbon
in sample was added to ceramic and pottery while production or while use - food preparation,
etc.) allows application of such materials for 14C dating i.e. by application of direct pyrolysis procedures
for benzene preparation for conventional analyses based on LSC.

Radiocarbon dating C-14 sample prices and cost:
( Sample costs for a carbon 14 analysis )
Base price for C-14 dating is 100 Euro per sample (03/01/2009)
#1: Routine One (separate) charcoal sample (5-10 g of Carbon or more) coming abroad costs: 100 Euro + 10 Euro for Customs formalities. When 10 similar samples - cost is 1000-10%Discount+10 Euro for Customs formalities all equals 910 Euro.
#2: Routine One (separate) charcoal sample containing (0.5-3.0 g of Carbon) coming abroad costs:150 Euro+10 Euro for Customs formalities. When 10 similar samples cost is 1500-10%Discount+10 Euro for Customs formalities all equals 1360 Euro.
When Sample's rate is not equal to 1,0 - for all cases, the base price should be multiplied to corresponding Sample's rate.
When High Precision - for both cases, the base price should be multiplied
to 1.5.
About submission:
"SCIENTIFIC SAMPLES - NO COMMERCIAL VALUE".
Do not claim a total value of more than US$10.
(PLEASE ask us details BEFORE of your samples SENDING).
Archaeometry -- applying of measurements to archaeology;
Environmentology -- the studying of ancient climatic, volcanic and geological
changes in a given area at a given time span;
Ecology -- studying of impact
of nuclear installation to Environment.
All above require radiocarbon analyses.
