Abstract
본 고안은 방사선(중성자,감마,베타)차폐방법에 관한것으로 파라핀 플라스틱 재질로 구성된 블럭이 조립되어 방사선을 적절하게 차폐함을 목적으로 한다.The present invention relates to a method of shielding radiation (neutron, gamma, beta), and a block made of a paraffin plastic material is assembled for the purpose of adequately shielding radiation.
이를 위하여 차폐체가 좌블럭(1),중간블럭(2),우블럭(3)이 구성되고 방사선 발생 구역에 블럭을 상하좌우로 연결하였을때 방사선이 투과하지 못하도록 틈새가 없는 구조로 하였으며, 여러개를 쌓아 차폐벽이 형성될수 있도록 구성한다.For this purpose, the shield is composed of a left block (1), a middle block (2), and a right block (3), and has a structure without gaps so that radiation cannot penetrate when blocks are connected to the radiation generating area up, down, left and right. It is configured to be stacked to form a shielding wall.
통상적으로는 방사선 감마·베타 차폐용으로 납이 사용되고 있었으나 중성자 차폐를 효과적으로 할 수 있는 차폐체가 만들어지지 않아 복합적인 방사선 차폐에 방법이 적절하지 못하였다.Conventionally, lead was used for radiation gamma and beta shielding, but a shield was not made to effectively shield neutrons, so the method was not suitable for complex radiation shielding.
중성자 차폐에는 질량이 비슷한 수소(H), 산소(O), 탄소(C)등 가벼운 원자번호의 함유량이 많은 물질이 효과가 좋아 파라핀계열 플라스틱으로 차폐 블럭을 구성하여 중성자뿐만 아니라 감마·베타선 등 복합된 방사선을 차폐할 수 있어 방사선 차폐에 용이한 효과를 갖는다.For neutron shielding, a material with a high content of light atomic number such as hydrogen (H), oxygen (O), and carbon (C), which is similar in mass, is effective, forming a shielding block made of paraffin-based plastic, and combining neutrons with gamma and beta rays The shielded radiation can be shielded and has an easy effect on radiation shielding.
Description
본 고안은 원자력 발전소나 방사성동위원소 취급시설에서 방사선(중성자·감마·베타) 차폐에 관한 것으로 방사선 작업시 파라핀 플라스틱(Paraffin Plastic) 차폐 블럭을 설치하여 방사선을 차폐함으로써 원자력 분야 종사자의 피폭을 방지 할수있는 파라핀 플라스틱으로 구성한 방사선 차폐 블럭에 관한 것이다.The present invention relates to the shielding of radiation (neutrons, gamma, beta) in nuclear power plants or radioisotope handling facilities. A radiation shielding block composed of paraffin plastic.
종래에는 원자력 발전소나 방사성동위원소 취급시설에서 발생하는 방사선 차폐에 밀도가 큰 납을 재료로 한 차폐체를 사용하였으나 납은 무거워 운반의 어려움과 다양한 모형으로 제품화 할 수 없고 또한 방사선 중성자는 부딪치면 다시 튀어 나오는 반사(Albedo) 현상이 있어 원자력 발전설비 운영 중에 발생되는 중성자 차폐에는 효과가 적었고 통상 납 차폐체만 사용함으로써 원자력관련 종사자가 중성자에 의한 방사선 피폭에 문제점을 갖고 있었다.Conventionally, a shield made of dense lead material was used for radiation shielding in a nuclear power plant or radioisotope handling facility. Because of the reflection phenomenon, the neutron shielding generated during the operation of the nuclear power plant was less effective. Usually, only the lead shield was used, and nuclear workers had problems with radiation exposure by neutrons.
원자력 발전소나 방사성동위원소 취급설비 가동중 기기 조작 또는 보수 작업시 방사선(중성자·감마·베타) 발생에 의한 작업종사자의 외부피폭을 방지하기 위함이다.This is to prevent external exposure of workers by radiation (neutron, gamma, beta) generation during operation or repair of equipment while operating nuclear power plants or radioisotope handling facilities.
원자력분야 방사선 발생구역에 방사선차폐체로 납이 일부 사용되고 있으나 중성자 차폐에 효과가 좋은 파라핀 계열 플라스틱 차폐체 블럭이 없슴Although some lead is used as a radiation shield in the radiation area of the nuclear field, there is no paraffin-type plastic shield block that is effective for shielding neutrons.
본 고안의 과제는 방사선 중성자가 열중성자에서 속중성자에 이르기까지 각각 에너지 분포가 넓다(0.01eV∼1000Mev) 특히 중성자는 전하를 가지고 있지않고, 원자핵과의 탄성충돌에 의하여 에너지를 잃는다.The problem of the present invention is that the radiation neutrons have a wide energy distribution from thermal neutrons to fast neutrons (0.01 eV to 1000 Mev). Especially, neutrons do not have electric charges, and energy is lost by elastic collision with the atomic nucleus.
중성자가 차츰 에너지를 잃어 열중성자(0.025eV)가 되면 양성자와 전자로 붕괴된다. 따라서 중성자의 차폐체로는 원자번호가 가벼운 물질인 파라핀, 플라스틱이 적절하다.When neutrons gradually lose energy and become thermal neutrons (0.025 eV) they decay into protons and electrons. Therefore, as the shield of neutrons, paraffin and plastic, which have light atomic number, are suitable.
통상 기존 차폐체는 감마 베타선을 차폐하기 위한 목적으로 납이나 콘크리트 등을 사용하기 때문에 중성자 차폐에는 적절치 못한 문제점을 해결하고자 하는 것이다.Conventional shielding is to solve the problem that is not suitable for neutron shielding because it uses lead or concrete for the purpose of shielding gamma beta-rays.
