Embodiment 1

[0047] Embodiment 1 of the present invention provides a portable self-powered radioactive cesium element enrichment sampling device, see image 3 , the device of this embodiment includes: a pre-filter 5, a water pump 1 comprising a gasoline engine 10, a pressure divider 7, a flow meter 8, a filter 6 comprising a primary filter and a secondary filter, comprising a primary enricher and the enricher 3 of the secondary enricher, each enricher 3 includes an adsorber 4 and a flow meter 9 .

[0048] Among them, in the working process of the device of this embodiment, it is first necessary to use such as Figure 4 The setup shown prepares the adsorber 4 . Figure 4 , including a plurality of preparers 11 , circulation pump 12 and circulation pump controller 13 , flow meter 14 and liquid storage tank 15 . The specific preparation steps of the adsorber 4 are as follows: first, the columnar microporous cotton medium is respectively put into a plurality of preparers 11, and deionized wa...

Embodiment 2

[0053] Embodiment 2 of the present invention provides a portable radioactive element enrichment sampling method according to the above-mentioned portable radioactive element enrichment sampling device, see Figure 5 ,include:

[0054] Step 501: using a water pump to extract water samples from the water body to be sampled, and make the water samples flow into the concentrator;

[0055] Step 502: Use the enricher including the adsorber to perform radioactive element enrichment sampling on the incoming water sample.

[0056] It can be seen that in the portable radioactive element enrichment sampling device and method provided in the embodiments of the present invention, environmental water samples can be directly collected, such as seawater, river water, lake water, reservoir water, etc. It can enrich the radioactive isotopes with very low content in the sample, and accumulate radioactive isotopes with sufficient activity to achieve subsequent measurement sensitivity, especially...

Abstract

The invention provides a portable device and method for radioactive element enrichment sampling. The device comprises a water pump and an enricher, wherein the water pump is used for drawing a water sample from water to be sampled and enabling the water sample to flow into the enricher; an absorber is arranged in the enricher, and the enricher is used for performing radioactive element enrichment sampling on an inflowed water sample by utilizing the absorber. Through the use of the device, the environmental water sample can be directly extracted, a radioactive isotope in a very low content in the environmental water sample is enriched, the radioactive isotope with enough activity is accumulated for achieving subsequent measuring sensitivity, and particularly the device is suitable for sampling and collecting a caesium isotope. The device replaces a traditional sampling method of transferring a big-volume water sample to a laboratory, and the device has the advantages that the size is small and exquisite, and the structure is compact, so that the device is convenient to carry and transport.

Description

technical field [0001] The invention relates to the field of nuclear science and technology, in particular to a portable radioactive element enrichment sampling device and method. Background technique [0002] With the rapid development of our country and the world economy, nuclear energy has become one of the irreplaceable main energy sources, and its proportion in the world's energy structure is increasing day by day. However, the most important risk brought by the use of nuclear energy is that it may cause radioactive pollution to the environment in an accident state. The direct consequence of this pollution is the threat to the living environment and food safety. The Chernobyl nuclear accident in the former Soviet Union in 1986 and the Fukushima nuclear accident in Japan in 2011 both left people with painful lessons and high costs. Due to the security of energy supply, my country is currently restarting its nuclear energy strategy, and the installed capacity of nuclear ...
