Embodiment Construction

[0065] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0066] The present invention utilizes the high-energy electron beam emitted by the high-power electron accelerator to bombard the conversion target to generate bremsstrahlung, and utilizes the bremsstrahlung and the sample target 100 Mo produced by photonuclear reaction 99 Mo, including 99 Mo's 100 The Mo sample target is automatically transferred to the hot chamber through the programmable robot system and the conveyor belt, and the Mo sample target is separated by the radiochemical separation procedure. 99 From 100 The Mo sample target was separated and purified. The photonuclear reaction in addition to the usual 100 Mo(γ,n) 99 Mo can be produced 99 In addition, the following photonuclear reactions also produce 99 Mo, a total of 5 photonuclear reactions occur simultaneously and co-produce 99 Mo.

[0067] 100 Mo(γ,n) 99 ...

Abstract

The invention belongs to the field of medical radioactive diagnosis and treatment nuclide, and particularly relates to a method and equipment for producing medical isotopes based on a high-power electron accelerator. The problems that in the prior art a method for producing 99Mo based on an accelerator is low in yield, 100Mo sample target machining difficulty is high, and other Tc isotope impurities can be generated are solved. High-energy electron beams emitted by the high-power electron accelerator are used for bombarding a conversion target to generate braking radiation; the braking radiation and a sample target are subjected to a photo-nuclear reaction to produce target medical isotopes, then the sample target containing the target medical isotopes is automatically transferred to a hotchamber by using a robot and a conveying belt, and the target medical isotopes are separated and purified from the sample target through a radiochemical separation procedure. The method is suitable for production of various medical radioactive isotopes such as 99Mo, 15O, 13N, 11C, 88Y, 123I, 125I, 111In, 57Co and 30P, 38K, 62Cu, 64Cu, 47Sc and 225Ac and the like.

Description

technical field [0001] The invention belongs to the field of medical radioactive diagnosis and treatment nuclides, in particular to a photonuclear reaction production based on bremsstrahlung and target substances of electron beams emitted by high-power electron accelerators 99 Methods and equipment for medical isotopes such as Mo. Background technique [0002] With the wide application of γ-camera and SPEC / CT, the imaging and diagnostic techniques of nuclear medicine, the tracer radiopharmaceuticals are also developing rapidly. The most commonly used and typical molybdenum-technetium generator ( 99 Mo- 99m Tc, hereinafter referred to as the cow). [0003] cow is 99 Mo, whose half-life is 66 hours, can cope with the separation from the place of production to the place of use 99m Decay consumption of Tc. 99m The γ-ray energy emitted by Tc is very low, and 140keV has little damage to the human body, and the imaging positioning is accurate. contain 99m There are as many ...
