  • This report of the National Council on Radiation Protection and Measurements (NCRP) , successor to the National Committee on Radiation Protection and hleasurements, is concerned with the spccification of sealed sources of nuclides which emit gamma rays-sources useful in brachytherapy. The report resulted from the Council's belief that a single well-defined method for specifying the radionuclide in an encapsulated source would be advantageous for both the users and the suppliers of such sources....

  • The Pest Risk Analysis on South American Leaf Blight, The Contingency Plan for South American Leaf Blight of Rubber and the Model Work Plan for the Importation of Budded Stumps or Budwood of Hevea are supporting documents for the implementation of the Regional Standards for Phytosanitary Measures No. 7 – Guidelines for Protection against South American Leaf Blight of Rubber. These documents reflect the most up-to-date progress of APPPC in terms of management of SALB and are essential references for protection against SALB in Asia and Pacific region.

  • Although the FHLBB legally had enforcement powers similar to those of the banking agencies, it used these powers much less frequently. 11 The S&L supervisory environment simply was not conducive to prompt corrective enforcement actions. As indicated above, S&Ls were traditionally highly regulated institutions, and before the 1980s the industry had exhibited few problems of mismanagement. The industry’s significant involvement in its own supervision stemmed from its favorable image and protected status with lawmakers. As one S&L lobbyist later wrote: “When we [the U.S.

  • : This equipment has been tested and found to comply with the limits for a class digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.

  • Personal protective equipment (PPE) includes clothing or other special equip- ment that is issued to individual workers to provide protection against actual or potential exposure to ionizing radiations. It is used to protect each worker against the prevailing risk of external or internal exposure in circumstances in which it is not reasonably practicable to provide complete protection by means of engineering controls or administrative methods. Adequate personal protection depends on PPE being correctly selected, fitted and maintained.

  • Shielding gloves and sleeves containing up to 0.33 mmPb are manufactured. Like aprons, they are ineffective shields against most radiations other than electrons (beta particles) and low energy scattered X rays. Wearing the gloves reduces dexterity and consequently, if used inappropri- ately, will result in significant hand doses and greater body doses by prolonging the exposure. The sleeves are flexible and, when used as local shielding, provide good cover for the extremities.

  • A new class of rugged fiber optic connectors has been introduced to speed residential connection in Fiber-To-The-Premises (FTTP) cabling networks. The connectors are strategically located in the distribution network to facilitate service connection, maintenance and reconfiguration of subscriber services. Connectors are typically staged at the street outside a residence to facilitate easy access and connection to the residence at a later date.

  • The production of melanin (tanning) accounts for part of the protection against UV radiation, but there is mounting scientific evidence that faculta- tive tan is triggered by UV-induced DNA damage in the skin (Pedeux et al., 1998; Gilchrest & Eller 1999 for a review). Facultative tanning is now considered a better indicator of inducible DNA repair capacity than of efficient photoprotective skin reaction. Inducible DNA repair capacity rather than pigmentation itself could result in the lower incidence of skin cancer observed in darker-skinned individuals (Young et al.

  • The radiation protection policies and implementing procedures suggested in this book were developed based on NRC regulations. They may not apply to diagnostic nuclear medicine facilities in Agreement States. It will be necessary, therefore, even for those wishing to adopt a template procedure in Agreement States, to review procedures against the medical use regulations and other requirements of their state.

  • The Joint Government Relations Committee of the American College of Nuclear Physicians and the Society of Nuclear Medicine recognized that nuclear medicine practitioners across the spectrum of diagnosis would value professional guidance in meeting the new outcomes require- ments. This book is intended to serve as a useful bridge between the new regulations and nuclear medicine practitioners who want to ensure continued compliance and maintain the security and safety of licensed materials in clinical and research settings.
