 | A radiation protection survey of the shielded NDI facility at Homestead ARB was conducted. The NDI facility used a Lorad LPX-160 x-ray unit for inspections. In addition, a survey of the Class IIIa lasers was included in the assessment. The survey was performed in accordance with T.O. 33B-1-1 and applicable Air Force standards. The NDI facility was recertified as a Shielded Facility. |

| A radon study was performed post-remediation to determine if the ambient levels present in Building 54 at Nellis AFB are greater than Air Force standards. Per AFI 48-148, Ionizing Radiation Protection, 21 September 2011, paragraph 5.3.1.1.3, the data from this study were used to determine if facilities must be mitigated for radon hazards. No results from this study were above the 4.0 pCi/L action level. |

|
| Summary and Conclusions: Survival of gamma-irradiated mouse bone marrow and primary human hematopoietic CD34+ cells was significantly enhanced by Delta-tocotrienol (DT3). DT3 dramatically induced Erk phosphorylation and decreased the DNA-damage marker gamma-H2AX foci formation. DT3 reversed the radiation-inhibited mTOR and S6 protein activation, and induced 4EBP-1 phosphorylation. Knockdown of Erk gene expression by siRNA abrogated DT3-induced mTOR phosphorylation, induced gamma-H2AX foci formation, and inhibited clonogenicity in CD34+ cells. In conclusion, ... |

| Objective. Angiotensin II (Ang II), a potent vasoconstrictor, affects the growth and development of hematopoietic cells. Mixed findings have been reported for the effects of angiotensin-converting enzyme (ACE) inhibitors on radiation-induced injury to the hematopoietic system. We investigated the consequences of different regimens of the ACE inhibitor captopril on radiation-induced hematopoietic injury. Materials and Methods. C57BL/6 mice were either sham-irradiated or exposed to Co60 total body irradiation (0.6 Gy/min). Captopril ... |

| The task of protecting soldier eyesight and battlefield optical sensors from potentially damaging effects of high-intensity light has stimulated interest in electro-optic (EO) materials such as EO chromophores inserted into polymeric material. A priori design of optimal EO chromophores of Army relevance requires the capability to calculate accurately both the linear absorption properties (in effect, the color) and non-linear optical (NLO) properties of EO chromophores. Here we discuss two major ... |

| A recent rash of incidents involving lasers aimed at aircraft cockpits has raised concerns over the potential threat to aviation safety and security. While none of these incidents has been linked to terrorism, security officials have expressed concern that terrorists may seek to acquire and use higher powered lasers to, among other things, incapacitate pilots. There is also growing concern among aviation safety experts that the ubiquity and low cost ... |

| Fluorinated Single Wall Nanotubes (f-SWNTs) have been processed in polyethylene by an incipient wetting technique to achieve a well dispersed nanocomposite for radiation protection. In some cases, samples were further processed using the rapid prototyping method of extrusion freeform fabrication. Composites were exposed to 40 MeV proton radiation with a flux of about 1.7x10(exp 7) protons/sq cm/sec to a total fluence of 3x10(exp 10) protons/sq cm. This exposure is consistent ... |

| Using cutting-edge technology to create a human factors advantage in military operations will contribute to success on the battlefield of the future whether below the surface, on the surface, in the air, or in space. Human factors system selection in the past has appeared to be arbitrary and intermittent, with no unifying vision and apparently little or no coordination between the military services. Mature, timely applied technology will reduce risk ... |

| Measurements of dose rates at 10 locations inside a radiologically contaminated CF Grizzly Light Armoured Vehicle were made at a French army facility. This permits calculation of the radiation protection factors for the locations inside the vehicle. The contaminated vehicle protection factors varied between 3.3 and 6.9, depending on position within the vehicle, averaging 5.7. These values are consistent with previous measurements made at DREO. These results were also used ... |

|
| Current laser eye protection devices (LEPDs) are dye-based or reflective. While both technologies block the laser wavelengths, reflective LEPDs generally transmit more visible light than do dye-based LEPDs. Consequently reflective LEPDs are generally superior to dye-based LEPDs for the sparse light conditions of night. Reflective LEPDs are also better at maintaining a constant color appearance which is important for tasks requiring recognition of color coded information such as reading color ... |

| Laser induced flashblindness is a recognized problem in military and non-military environments. While there are active research programs on laser eye effects, and a laser hazard protocol has been generated by the civilian and military communities, they do not provide a vehicle for demonstrating, training and testing various laser eye protection procedures and equipment. Clearly a requirement exists for a portable, self-contained system that has an integrated visible laser unit ... |

| In its 1990 recommendation regarding occupational exposure during pregnancy, the International Commission on Radiological Protection apparently assumed that the equivalent dose to a pregnant woman's abdomen is reduced by half in traversing the body to the conceptus. This assumption was tested with respect to galactic cosmic radiation, the principal ionizing radiation to which aircrews are exposed. We calculated the equivalent dose that would be received at depths of 0, 5, ... |

| Tissue equivalent proportional counters (TEPC) have been used to measure energy deposition in simulated volumes of tissue ranging in diameter from 0.1 to 10 microns. There has been some concern that the wall used to define the volume of interest could influence energy deposition within the sensitive volume. These 'wall effects' occur because the wall has a density significantly greater than the cavity gas. Energy deposition measurements were made for ... |

| Laser eye protection was first introduced into the U.S. Fleet when the need arose to protect aviators and aircrew from our own neodymium systems. This protection was designed to reduce the incidence energy below the maximum permissible exposure level established by the American National Standards Institute. Since range finders used an infrared wavelength, as defined and therefore not visible to the eye, there was no possibility of glare. With time ... |
