cell processes, i.e., DNA, RNA, proteins
34. Delayed Effects of Radiation
• Cataracts
are induced when a dose exceeding
approximately 200-300 rem is delivered to the lens of the
eye and may take months or years to appear

43. Minimal Threat Devices
• Radiation is contained inside the device
• Safety devices are employed to prevent exposure
44. Minimal Threat Devices
• Radiation is contained inside the device
• Safety devices are employed to prevent exposure
• Radiation at the device is the same as background radiation
45. Minimal Threat Devices
• Radiation is contained inside the device
• Safety devices are employed to prevent exposure
• Radiation at the device is the same as background radiation
• Safety checks are made regularly
48. ALARA
• As Low As Reasonably Achievable
• If
any radiation levels above background radiation are
observed, appropriate steps are taken to reduce radiation
51. Summary
• Radiation is regulated because of health hazards
• X-rays are a form of energy like light, only invisible
52. Summary
• Radiation is regulated because of health hazards
