Radioactive lenses  核辐射镜头列表（毒镜2024-9-5更新）

 

经常玩老镜头的一定要知道，有些早期的镜头是含有辐射的 ，主要是电离辐射 也就是我们常说的核辐射。区别于日常生活中的电磁辐射，电磁辐射是明确对身体有危害的，虽然危害的等级以及后果不确定，但是我们要清楚的了解自己所用的镜头是否存在问题。以下文章来源于国外的wiki专门收集了辐射镜头的列表。用来给大家日常参照。
有从1940年通过，测量放射性年代大量生产的镜头。放射性的来源主要是 氧化钍 使用（30%重量）作为镜片玻璃组件。氧化钍具有类似氟化钙（萤石）的晶体结构。像萤石，其光学性能的高折射率、低色散镜头设计者允许减少 色差 利用低曲率的镜片，这是更便宜的生产。与通常情况相反的是，含有镧的透镜没有明显的放射性——镧只有1／第一万，像钍一样具有放射性。含镧透镜的放射性是由于在光学玻璃混合物中有意掺入钍。钍的存在有时取决于透镜中其他元素的混合，导致透镜元素的中度到严重的褐变。

There are a significant number of lenses produced from the 1940s through the 1970s that are measurably radioactive. Main source of radioactivity is the use of thorium oxide (up to 30% by weight) as a component of the glass used in the lens elements. Thorium oxide has a crystalline structural similar to calcium fluoride (fluorite). Like fluorite, its optical properties of high refractivity and low dispersion allows lens designers to minimize chromatic aberration and utilize lenses of lower curvature, which are less expensive to produce. Contrary to often seen statements to the otherwise, lenses containing lanthanum are not appreciably radioactive – lanthanum is only 1/10,000th as radioactive as thorium. Radioactivity in lanthanum containing lenses is due to the intentional inclusion of thorium in the optical glass mix. The presence of thorium can sometimes, depending on the mixture of other elements in the lens, cause moderate to severe browning of the lens elements.

Radiation Levels

典型的辐射水平在镜头元素的表面可以达到10毫西弗/小时（100微米/小时），随着距离的增加而大幅下降；在3英尺（90厘米）的距离上，辐射水平很难在典型的背景水平上探测到。作为参考，一个典型的胸部X光片由大约10先生，往返越野飞行暴露了旅客5先生，和全套 牙科X射线 暴露病人10先生40mr。
大多数带有钍元素的小透镜并不十分危险。然而，钍的目镜是危险的。他们可以给眼睛的角膜提供一个非常大的α和β粒子剂量，导致白内障和其他问题。正常情况下，这些颗粒被皮肤阻挡，但眼睛表面很快被它们破坏，而且在近距离，剂量可能非常高

Typical radiation levels can approach 10 mR/hr (100 μSv/h) as measured at the lens element’s surface, decreasing substantially with distance; at a distance of 3 ft. (.9 m.) the radiation level is difficult to detect over typical background levels. For reference, a typical chest x-ray consists of about about 10 mR, a round-trip cross country airline flight exposes a passenger to 5 mR, and a full set of dental x-rays exposes the patient to 10 mR to 40mR.

Most smaller lenses with thorium elements are not very dangerous. However, thorium eyepieces are dangerous. They can give a very large alpha and beta particle dose to the cornea of the eye, causing cataracts and other problems. Normally these particles are stopped by skin, but the surface of the eye is quickly damaged by them, and at close range, the dose can be very high.

Kodak Lenses

到目前为止，生产最多的放射性镜头是伊士曼·柯达。从20世纪40年代到60年代，业余相机的大量生产和销售（含钍钍氧化物）的镜头，包括一些对 小马， 图章，高端 傻瓜 （例如800和 814，而不是100或124  ） 相机。此外，很多专业级艾克塔镜头从这个时代包含钍。也许最著名的放射性的镜头都ektars 柯达航空。
奇怪的是，在他著名的书， 一摄影镜头的历史，鲁道夫·京斯莱克（伊士曼柯达镜头设计部门1937-1968头），只有一个路过的评论使用柯达眼镜可能使钍。

By far the most prolific producer of radioactive lenses was Eastman Kodak. From the 1940s through the 1960s, substantial numbers of amateur cameras were produced and sold with thoriated (containing thorium oxide) lenses, including some of the Pony, Signet, and high end Instamatic (e.g. 800 and 814, but not 100 or 124) cameras. In addition, many professional level Ektar lenses from this era contain thorium. Perhaps the most famous radioactive lenses of all were the Kodak Aero-Ektars.

Curiously, in his notable book, A History Of The Photographic Lens, Rudolf Kingslake (head of the Eastman Kodak lens design department 1937-1968), makes only a single passing comment on the possible use of thorium in Kodak lenses.

    • 与通常的看法相反，早期的8元素超级塔库玛（Super Takumar）也具有放射性：https : //www.youtube.com/watch?v= yqLv6ngbJ7Y 除了这里显示的镜头之外，我还测试了2个其他镜头的β和γ粒子，从而获得了读数在后面的速度高达约1.2-1.35 µSv / h，在前面的速度约为0.2 µSv / h（背景辐射约为0.14 µSv / h）。所有3个镜头都经过验证，属于8元素类型：除了具有所有外部特征之外，我还为它们提供了服务，因此我可以算要素。放射性元素在后面，而不是在前面。好消息是，数码相机后盖（例如，索尼Alpha 7RII）有效地阻止了来自后部的所有辐射。不幸的是，对于放射性更高的7元素镜片而言并非如此。
    • 本文是关于镧或Thor的Alpha辐射，而不是Beta或Gamma辐射 [False。本文涉及所有辐射类型] 。您可能会对其他类型的辐射测试呈阳性，但这并不意味着它们都可以 [无意义。无法测试镜头的所有副本。如果您测试3份并发现它们全部具有放射性，那么可以断定该镜片具有放射性是明智的] 。其他几个收集者从其示例中检测到任何形式的零辐射，请不要过分概括 [这些“收集者”是谁，这些主张的证据在哪里？此页面应仅包含有证据支持的陈述]
    • 我的8个镜头也具有放射性。此处的视频-https :  //youtu.be/Spl5mUqAcOs
    • Contrary to common belief, the early 8-element Super Takumar too is radioactive: https://www.youtube.com/watch?v=yqLv6ngbJ7Y Besides the lens shown here, I have tested 2 others for beta & gamma particles, getting readings at the back of up to about 1.2-1.35 µSv/h and at the front of about 0.2 µSv/h (against a background radiation of about 0.14 µSv/h). All 3 lenses have been verified to be of the 8 elements type: besides having all external characteristics, I serviced them, so I could count the elements. The radiactive elements are those at the back, not at the front. The good news is that all radiation from the rear is effectively stopped by a digital camera back (e.g. Sony Alpha 7RII). This is unfortunately not the case for the much more radioactive 7-element lenses.
    • This article is about Alpha radiation from Lanthanum or Thorium, not about Beta or Gamma radiation [False. This article is about all radiation types]. Yours may test positive for other types of radiation, but that doesn’t mean that they all do [Nonsense. It’s impossible to test all copies of a lens. If you test 3 copies & find them all radioactive, it’s sensible to conclude the lens is radioactive]. Several other collectors have detected zero radiation of any kind from their examples, please do not over-generalize [Who are these ‘collectors’ and where is the evidence for these claims? This page should contain only statement supported by evidence]

Lenses with elements made of contaminated glass

20世纪60年代的一些镜片有玻璃元素组成，包括微量的放射性稀土元素。有时这种偶然的放射性会导致这些透镜元素的显著泛黄。这些镜头的一些用户在照相机博客中报道说，他们将这些镜片暴露在太阳的紫外线下，从而治愈了泛黄。这个程序需要几天的晴天才能产生积极的效果。具有这种泛黄放射性杂质的透镜元件在以下透镜中：

Some lenses of the 1960s have elements made of glass sorts which include small traces of radioactive rare-earth elements. Sometimes this accidental radioactivity causes a significant yellowing of these lens elements. Some users of such lenses reported in camera blogs that they healed the yellowing by exposing these lenses to the ultraviolet light of the sun. The procedure needs several days of sunny weather to have a positive effect. Lens elements with such yellowing radioactive impurity are in the following lenses:

  • Minolta MC W. Rokkor-SI 1:2.5 28mm (early variant, before radioactive glass impurity could be banned)
  • Minolta MC Rokkor-PG 1:1.2 58mm (early variant, before radioactive glass impurity could be banned)
  • Minolta MC Rokkor 1:1.7 85mm (the earliest variant of the MC line) http://www.dg77.net/photo/x500/mc85.htm

泛黄的阳光愈合也有报道用钍玻璃元素的一些镜头，比如尼克尔35mm的f / 1.4镜头和超级手动50mm f/1.8 $ 1.4镜头。

The healing of yellowing by sunlight is also reported for some lenses with thorium glass elements, for example for the Nikkor 35mm f/1.4 lens and the Super Takumar 50mm f/1.4 lens.
