00:00:01,920 --> 00:00:07,240
Speaker 1: Welcome to brain stuff production of iHeart radio Hey brain

2
00:00:07,240 --> 00:00:11,640
Speaker 1: stuff learned bolba blam here way before its radioactive properties

3
00:00:11,680 --> 00:00:15,760
Speaker 1: were discovered and exploited for both good I think nuclear

4
00:00:15,800 --> 00:00:20,360
Speaker 1: power and bad think nuclear war, and way before it

5
00:00:20,400 --> 00:00:23,079
Speaker 1: was officially granted its place among the elements of the

6
00:00:23,120 --> 00:00:27,640
Speaker 1: periodic table. The rare metal uranium was used by ancient

7
00:00:27,760 --> 00:00:32,640
Speaker 1: Romans to color glass back in seventy nine or so,

8
00:00:33,159 --> 00:00:37,519
Speaker 1: and neither radioactivity nor uranium meant anything to the Romans

9
00:00:37,920 --> 00:00:42,120
Speaker 1: or anyone The concepts as such simply didn't exist yet

10
00:00:42,560 --> 00:00:45,680
Speaker 1: neither did Uranus, the planet for which uranium is named.

11
00:00:45,720 --> 00:00:50,040
Speaker 1: For that matter, but the small glowing glass tiles in

12
00:00:50,159 --> 00:00:56,280
Speaker 1: some mosaics and tricked out Roman villas they were pretty cool. Yes,

13
00:00:56,560 --> 00:00:59,920
Speaker 1: the Romans used uranium in their glass, and the mode

14
00:01:00,240 --> 00:01:02,960
Speaker 1: versions of the stuff still exists. It goes by a

15
00:01:03,000 --> 00:01:05,760
Speaker 1: few different names and is even still being produced in

16
00:01:05,840 --> 00:01:08,800
Speaker 1: small quantities in Europe, but it's more of a curio

17
00:01:08,880 --> 00:01:11,839
Speaker 1: now than anything else, found in the form of pictures

18
00:01:11,880 --> 00:01:16,039
Speaker 1: and bowls and other glassware in flea markets, dusty attics, museums,

19
00:01:16,080 --> 00:01:20,800
Speaker 1: and among glass collectors. Glass to achieve added uranium will

20
00:01:20,800 --> 00:01:24,840
Speaker 1: look translucent, yellowish green under normal light, or it can

21
00:01:24,880 --> 00:01:28,679
Speaker 1: be colored other shades of translucent or opaque, but under

22
00:01:28,760 --> 00:01:33,520
Speaker 1: ultraviolet light it fluoresces bright green. I think the color

23
00:01:33,720 --> 00:01:37,520
Speaker 1: used for Nuclear Goo and Atomic Age, horror illustrations, or

24
00:01:37,720 --> 00:01:41,720
Speaker 1: the Ninja Turtles or the Simpsons. For the article this

25
00:01:41,760 --> 00:01:44,800
Speaker 1: episode is based on How Stuff Works. Spoke with Paul Frame,

26
00:01:45,000 --> 00:01:49,080
Speaker 1: a retired health physicist at Tennessee's oak Ridge Associated Universities,

27
00:01:49,360 --> 00:01:52,080
Speaker 1: which is a consortium of schools founded after World War

28
00:01:52,120 --> 00:01:56,560
Speaker 1: Two as the oak Ridge Institute of Nuclear Studies. For years,

29
00:01:56,600 --> 00:01:59,840
Speaker 1: Frame was also the curator at the consortium's Health Physics

30
00:02:00,040 --> 00:02:04,120
Speaker 1: Historical Instrumentation Museum, also known as the Museum of Radiation

31
00:02:04,120 --> 00:02:08,400
Speaker 1: and Radioactivity, which chronicles the scientific and commercial history of

32
00:02:08,520 --> 00:02:14,320
Speaker 1: radioactivity and radiation. Frame said, it is kind of attractive

33
00:02:14,400 --> 00:02:17,160
Speaker 1: because it has that ear doesn't glow to it under

34
00:02:17,160 --> 00:02:21,280
Speaker 1: certain lighting conditions. It really looks kind of special. There

35
00:02:21,280 --> 00:02:23,880
Speaker 1: are some people out there that are particularly interested in

36
00:02:23,919 --> 00:02:26,959
Speaker 1: it because it's radioactive, and there are other people who

37
00:02:27,120 --> 00:02:31,840
Speaker 1: just collect glassware, the styles and so forth. But there's

38
00:02:31,880 --> 00:02:34,360
Speaker 1: so much of this stuff out there that despite the

39
00:02:34,400 --> 00:02:36,640
Speaker 1: fact that there's a variety of people that are interested

40
00:02:36,680 --> 00:02:38,640
Speaker 1: in it, it really doesn't have a lot of value

41
00:02:38,720 --> 00:02:43,040
Speaker 1: unless it's a particularly unique piece of glassware, size, design, artistry,

42
00:02:43,200 --> 00:02:46,560
Speaker 1: that kind of thing. Uranium glass is also known as

43
00:02:46,680 --> 00:02:51,080
Speaker 1: vasoline glass because that translucent yellowish green reminded some people

44
00:02:51,120 --> 00:02:55,399
Speaker 1: of Vasoline brand petroleum jelly, and it certainly has its

45
00:02:55,440 --> 00:02:59,440
Speaker 1: die hard fans. Some collectors and deficionados of the stuff

46
00:02:59,560 --> 00:03:03,240
Speaker 1: gather every year for conventions to buy, sell, show off,

47
00:03:03,320 --> 00:03:07,000
Speaker 1: and learn about uranium glass pieces. One convention was in

48
00:03:07,040 --> 00:03:12,200
Speaker 1: its twenty second year. In addition, some antique shops and

49
00:03:12,280 --> 00:03:17,320
Speaker 1: exchanges feature large collections of the glowing, sometimes eerie looking glass.

50
00:03:18,440 --> 00:03:21,880
Speaker 1: Uranium was identified as an element in sevent nine, and

51
00:03:22,000 --> 00:03:26,240
Speaker 1: Austrian glassmakers are credited with knowingly producing the first uranium

52
00:03:26,240 --> 00:03:30,000
Speaker 1: glass around eighteen thirty. In World War Two, the US

53
00:03:30,080 --> 00:03:33,200
Speaker 1: government restricted the use of uranium for coloring glass. It

54
00:03:33,280 --> 00:03:36,000
Speaker 1: was thought that the uranium might be needed for nuclear weapons,

55
00:03:36,360 --> 00:03:39,279
Speaker 1: a band that lasted until the latter part of ninety

56
00:03:41,040 --> 00:03:46,280
Speaker 1: which brings us to an interesting question. Is uranium glass radioactive?

57
00:03:47,600 --> 00:03:52,640
Speaker 1: In a word, yes, uranium glass is indeed radioactive. That said,

58
00:03:52,680 --> 00:03:55,000
Speaker 1: there's no need to run for the hills or the

59
00:03:55,080 --> 00:03:59,680
Speaker 1: nearest bomb shelter frame said it's absolutely true we're dealing

60
00:03:59,760 --> 00:04:03,240
Speaker 1: with with vaseline glass is something that is radioactive just

61
00:04:03,360 --> 00:04:06,800
Speaker 1: like everything else, and it is more radioactive than the

62
00:04:06,840 --> 00:04:10,160
Speaker 1: majority of things, and that you can detect the radioactivity

63
00:04:10,280 --> 00:04:13,840
Speaker 1: of vassline or uranium glass with a handheld meter like

64
00:04:13,880 --> 00:04:17,880
Speaker 1: a Geiger counter. Is the radioactivity from uranium glass strong

65
00:04:18,000 --> 00:04:22,039
Speaker 1: enough to say, morph someone into a big green, angry

66
00:04:22,040 --> 00:04:25,400
Speaker 1: guy or a part kid, part a rachnoid, or strong

67
00:04:25,520 --> 00:04:29,400
Speaker 1: enough to make you sick or kill you. Basically, no

68
00:04:30,520 --> 00:04:34,120
Speaker 1: Frame offered up a quick history lesson, he said. Marie

69
00:04:34,160 --> 00:04:37,280
Speaker 1: Curry got these more residues from the Czech Republic back

70
00:04:37,279 --> 00:04:40,560
Speaker 1: in the day, and she extracted the uranium, but discovered

71
00:04:40,600 --> 00:04:43,320
Speaker 1: what was left behind was even more radioactive than the

72
00:04:43,440 --> 00:04:47,800
Speaker 1: uranium itself. The material that made the residues most radioactive

73
00:04:47,920 --> 00:04:51,800
Speaker 1: turned out to be radium, not the uranium. So in

74
00:04:52,000 --> 00:04:55,440
Speaker 1: uranium or you have this whole host of radioactive stuff

75
00:04:55,640 --> 00:04:58,719
Speaker 1: and the key player there is really radium. A radium

76
00:04:58,720 --> 00:05:05,479
Speaker 1: to uranium itself is not all that radioactive. Still Frame

77
00:05:05,480 --> 00:05:08,880
Speaker 1: will admit there may be some incredibly small risk involved

78
00:05:08,920 --> 00:05:13,120
Speaker 1: with uranium glass. He said, it's basically a theoretical risk.

79
00:05:13,520 --> 00:05:16,640
Speaker 1: The radioactive exposures you get from flying in an airplane

80
00:05:16,760 --> 00:05:19,279
Speaker 1: or inhaling air in your home which has rate on

81
00:05:19,279 --> 00:05:22,000
Speaker 1: in it, they're so much greater than any dose that

82
00:05:22,040 --> 00:05:25,600
Speaker 1: anyone's going to get from uranium or vasoline glass. There is,

83
00:05:25,680 --> 00:05:30,480
Speaker 1: for all practical purposes no risk, zero risk, which for

84
00:05:30,680 --> 00:05:34,800
Speaker 1: collectors and admirers is good news, because blast that glows

85
00:05:35,160 --> 00:05:44,320
Speaker 1: is just cool. Today's episode is based on the article
