Description
Technical field
The utility model relates to a kind of radioactive waste treatment devices, more particularly to a kind of useless containing organic tritium carbon 14
Gurry processing unit.
Background technique
Labeled compound is to enable it to be identified with one or more of atoms of radionuclide substituted compound molecule
And it can be used as the compound of tracer.It and unlabelled respective compound chemistry having the same and biological property are different
Only it have radioactivity, thus can be tracked using radioactivity prospecting technology.As hydrogeneous in amino acid molecular, H can be used3,
This marker is introduced in organism again, then the isotope in these markers will be as corresponding common atom, in biology
Transport, transfer and participation metabolic activity in body.Radiolabeled atom is easy to recognize, and is based on radioactive isotope
With can the frequently spontaneously characteristic of emitting radiation, and radioactive ray are easy to track discovery by electron detection instrument, thus
It shows their position and quantity, so radioactive isotope introduces after organism, seems the mark for having had conduct, therefore again
It is radioactive tracer.
There is nuclear reactor since the 1940s and supplies (the form BaCO of carbon 14 with3) rise, begin to carbon
Development, production and the application of 14 labeled compounds.Later as the radioactivity such as hydrogen 3 (tritium), I125, iodine 131, S35, P 32 are same
The appearance of position prime quotient's product, the development of corresponding labeled compound, production and application also rapidly develop, the beginning of the eighties, in the world with
The labeled compound that commercial form is sold, including amino acid, polypeptide, protein, carbohydrate, nucleotide, nucleosides, purine, pyrimidine, steroid
Race, the tumour antigen of lipids and medical research, hormone, receptor, vitamin and drug etc., kind is up to 2000
It is a variety of, wherein being occupied the majority with carbon 14 and tritium-labeled compound.
During medicament research and development, for the animal of the container of labeled drug contact, syringe needle and the medicinal object of test, all at
For radioactive waste, in clinical test, it is also desirable to evaluate radiopharmaceutical, therefore for the aspiration of drug reagent
The discharge of person, the article of contact will carry out corresponding radiological assessment.If it is radioactive waste, it is also desirable to corresponding place
It sets.
Radwastes treatment instigates radioactive waste suitable for all of final disposal (including past atmosphere or discharge into water)
Operating practice, such as collection, classification, concentration, burning, compression, decontamination, solidification, packaging, storage and transport etc..Waste processing
Target is to try to the volume of reduction radioactive waste, to reduce the expense of storage, transport and disposition, and recycling or multiple as far as possible
With reducing the discharge to environment.The radioactivity total amount and concentration of discharge have to comply with pertinent regulations.Waste must categorised collection and
Storage, handles respectively, prevents the diffusion of cross contamination or pollution.
From after 2008, the country supervises organic 14 emphasis of tritium carbon.Current all new nuclear power stations periphery carries out
It when environmental exact details is investigated, requires and organic tritium carbon 14 in biology and phytosphere is monitored and data summarization, assess nuclear power
Influence of the effluent tritium carbon 14 to biosphere after operation.After Fukushima Nuclear Power Accident, State Ministry of Environmental Protection requires to reinforce to environmental monitoring.
Currently, typical extracting method is high-temperature oxydation burning extraction method, specifically: after organism sampling back, it is freeze-dried,
The extraction that organic tritium carbon 14 is carried out by organic 14 extraction element of tritium carbon, the water and CO of absorption2It is measured after conversion；Plant
It after sample is returned, is dried by equipment such as baking ovens, after proposing inorganic water, is carried out by organic 14 extraction element of tritium carbon
The extraction of organic tritium carbon.Since the level of Environmental Tritium and carbon 14 is relatively low, the content for remaining in the tritium in organism is lower, because
This is needed using large capacity, 14 extraction element of easy decontamination, organic tritium easy to operate and organic carbon.Since organic tritium carbon 14 monitors
Belong to emerging monitoring, domestic at present to come into effect the unit of detection and few to organic tritium carbon 14, therefore, organic tritium carbon 14 extracts
Such monitoring can not quickly be carried out after device buying, it is also necessary to which relevant equipment provides unit and provides corresponding method progress
Effective organic tritium carbon 14 extracts.
It is earliest into domestic, the instrumentation tubes of this equipment by the organic tritium carbon extraction element of the first generation of representative of RADDEC
Only 10mm, sample-loading amount is unsatisfactory for the demand of biosphere monitoring less than 2g at all, domestic at present seldom to have user's purchase again.With
MTT12/65/900 is that organic 14 extraction element of tritium carbon of the second generation of representative is Shanghai Yi Xing mechanical & electronic equipment corporation, Ltd and Suzhou
Thermal technology institute customized improved equipment on the basis of RADDEC and MTT12/38/850, at that time in view of sample-adding amount will increase to 40g,
15g water sample can be extracted to meet a sample, but finds to lead due to the simplification of absorption plant in later use process
Caused absorption efficiency unstable, and dual temperature area cause sample catalysis burning and it is insufficient.With OTCS11/3 (RS120/1000/
11) it is made of for organic 14 extraction element of tritium carbon of the third generation of representative heating system, cooling system and extraction system, suitable for having
Machine solid sample combustion experiment, by oxidation reaction twice, the content of tritium and carbon 14 in test sample.Zhong Fu institute teacher Yang Huaiyuan
Organic 14 extraction element of tritium carbon of independent development causes sample to be likely to occur two kinds of feelings using single-ended air inlet due to single-ended air inlet
Condition: one, fierce burning causes sample to be gone out, two, burning it is insufficient.
