JOAN CARTAN-HANSEN,

3
00:00:06,533 --> 00:00:08,166
HOST: NUCLEAR TECHNOLOGY GETS

4
00:00:08,166 --> 00:00:10,433
USED IN LOTS OF DIFFERENT WAYS.

5
00:00:10,433 --> 00:00:11,900
SMOKE DETECTORS WORK BY USING A

6
00:00:11,900 --> 00:00:13,100
SMALL AMOUNT OF RADIOACTIVE

7
00:00:13,100 --> 00:00:14,900
MATERIAL TO IDENTIFY SMOKE

8
00:00:14,900 --> 00:00:16,500
PARTICLES.

9
00:00:16,500 --> 00:00:18,233
SOME FOODS ARE IRRADIATED TO

10
00:00:18,233 --> 00:00:20,100
KEEP THEM FROM SPOILING.

11
00:00:20,100 --> 00:00:21,533
SOME BUILDERS USE NEUTRON BEAMS

12
00:00:21,533 --> 00:00:24,266
TO LOOK INSIDE METAL STRUCTURES.

13
00:00:24,266 --> 00:00:25,800
DOCTORS USE RADIOACTIVE MATERIAL

14
00:00:25,800 --> 00:00:28,000
TO DIAGNOSE DISEASES AND TO KILL

15
00:00:28,000 --> 00:00:29,800
CANCER CELLS.

16
00:00:29,800 --> 00:00:30,900
GAMMA RADIATION IS USED TO

17
00:00:30,900 --> 00:00:33,066
STERILIZE MEDICAL PRODUCTS THAT

18
00:00:33,066 --> 00:00:34,066
WOULD BE DAMAGED BY HEAT

19
00:00:34,066 --> 00:00:35,800
STERILIZATION.

20
00:00:35,800 --> 00:00:37,000
SCIENTISTS USE NATURALLY

21
00:00:37,000 --> 00:00:38,433
OCCURING RADIOACTIVE MATERIAL TO

22
00:00:38,433 --> 00:00:39,800
CARBON DATE OR TO FIND THE AGE

23
00:00:39,800 --> 00:00:41,967
OF AN ANCIENT DISCOVERIES.

24
00:00:41,967 --> 00:00:43,100
EVEN SPACE CRAFTS USE

25
00:00:43,100 --> 00:00:44,533
RADIOACTIVE MATERIAL IN

26
00:00:44,533 --> 00:00:46,000
SCIENTIFIC DEVICES AND FOR

27
00:00:46,000 --> 00:00:47,867
ELECTRICITY AND HEAT.

28
00:00:47,867 --> 00:00:49,066
