1 L4007-1 Radiation Protection Division CHPPM-EUROPE RADIATION PROTECTION DIVISION Nonionizing Radiation Protection

2 L4007-2 Radiation Protection Division REFERENCES l AR 40-5, Preventive Medicine l AR 40-46, Control of Health Hazards from Lasers and other High Intensity Optical Sources l Department of Defense Instruction (DoDI) 6055.11, Protection of DoD Personnel from Exposure to Electormagnetic Fields (EMF) at Radio Frequencies (RF) from 3 kHz to 300 GHz l Title 21, Code of Federal Regulations, Laser Products

3 L4007-3 Radiation Protection Division Outline l Ionizing vs. Nonionizing Radiation l Biological Effects l Typical Nonionizing Systems in DOD l Control Measures

4 L4007-4 Radiation Protection Division Ionizing vs Nonionizing Radiation l Ionizing Radiation – Higher energy electromagnetic waves (gamma) or heavy particles (beta and alpha). – High enough energy to pull electron from orbit. l Nonionizing Radiation – Lower energy electromagnetic waves. – Not enough energy to pull electron from orbit, but can excite the electron.

5 L4007-5 Radiation Protection Division Examples on Nonionizing Radiation Sources l Visible light l Microwaves l Radios l Video Display Terminals l Power lines l Radiofrequency Diathermy (Physical Therapy) l Lasers MICROWAVE GAMMA ULTRA V VISIBLE INFRARED TV AM RF

6 L4007-6 Radiation Protection Division Biological Effects l Radiofrequency Ranges (10 kHz to 300 GHz) – Effects only possible at ten times the permissible exposure limit – Heating of the body – Cataracts – Developing fetus is at no greater risk than mother

7 L4007-7 Radiation Protection Division Biological Effects l Lasers – Permanent Eye Injuries – Cataracts and temporary blinding – Skin damage

8 L4007-8 Radiation Protection Division Typical DoD Nonionizing Systems l Radiofrequency – Microwave communications – Electronic Warfare Devices – Radar l Laser – Laser Pointers – Target Designators – Range Finders

9 L4007-9 Radiation Protection Division Control Measures l Radiofrequency – Maximum 10 mW/cm2 Power Density (most systems) – Controlled Areas – Inventory – Read Technical Manuals!!! – Hazard Criteria (TB 43-0133) – SOP – Surveys by CHPPM-EUR

10 L4007-10 Radiation Protection Division Control Measures l Laser – Classes 1, 2, 3a, 3b, 4 – Do not look into lasers. – Avoid reflective surfaces. – Medical SOP – Read Technical Manuals – Hazard Criteria (TB 43-0133) – Surveys by CHPPM-EUR

11 L4007-11 Radiation Protection Division Control Measures l Any other nonionizing radiation concerns, call CPT Hart, CHPPM-EUR, 486-7038.

12 L4007-12 Radiation Protection Division Overexposure Procedures l See Attached sheets

13 L4007-13 Radiation Protection Division Summary l Ionizing vs. Nonionizing Radiation l Biological Effects l Typical Nonionizing Systems in DOD l Control Measures

14 L4007-14 Radiation Protection Division Questions
