伽马射线 Gamma ray

(重定向自Gamma Radiation)
伽马射线
α粒子相当于氦的原子核可被纸所阻挡,β粒子相当于电子可被铝箔所阻挡,γ射线则具有高穿透性。

伽玛射线(英文:Gamma ray),或γ射线是原子衰变裂解时放出的射线之一。此种电磁波波长在0.01奈米以下,穿透力很强,又携带高能量,容易造成生物体细胞内的脱氧核糖核酸(DNA)断裂进而引起细胞突变、造血功能缺失、癌症等疾病。它可以杀死细胞,因此也可以作医疗之用,杀死癌细胞。

1900年由法国科学家P.V.维拉德(Paul Ulrich Villard)发现,他将含镭的氯化钡通过阴极射线,从照片记录上看到辐射穿过0.2毫米的铅箔,拉塞福称这一贯穿力非常强的辐射为γ射线,是继α射线、β射线后发现的第三种原子核射线。1913年,γ射线被证实为是电磁波,由原子核内部自受激态至基态时所放出来,波长短于0.2 埃,和X射线特性相似但具有比X射线还要强的穿透能力。γ射线通过物质并与原子相互作用时会产生光电效应、康普顿效应和正负电子对效应。γ射线即使使用较厚材料阻挡一般也仍然有部分射线泄漏,所以通常只能用半吸收厚度来定量材料的阻隔效果。半吸收厚度是指入射射线强度减弱到一半时阻隔物体的厚度。半吸收厚度其数值d(1/2)=ln2/μ≈0.693/μ,μ表示阻隔物材料的射线吸收系数。材料的射线吸收系数与射线频率、能量以及材料种类有关,一般原子序数高和密度高的元素构成的材料其γ射线吸收系数也较高。普通放射源如Cs-137放射源产生的γ射线在铝、铁、铜、铅中的半吸收厚度分别约为3.2cm、2.6cm、1.4cm和0.6cm。

Gamma ray 伽马射线

(重定向自Gamma Radiation)
Illustration of an emission of a gamma ray (γ) from an atomic nucleusGamma rays are emitted during nuclear fission in nuclear explosions.
This animation tracks several gamma rays through space and time, from their emission in the jet of a distant blazar to their arrival in Fermi's Large Area Telescope (LAT).

Gamma ray (also called gamma radiation), denoted by the lower-case Greek letter gamma (γ or \gamma ), is extremely high-frequency electromagnetic radiation and therefore consists of high-energy photons. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays. Rutherford had previously discovered two other types of radioactive decay, which he named alpha and beta rays.
