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.
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 industrys 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.
