When you rise in the morning, form a resolution to make the day a happy one to a fellow-creature.--Sydney Smith

Area Code Changes for RSIC

The East Tennessee area code is changing from 615 to 423. Some of our readers have noted the change already in the newsletter masthead. From September 11, 1995, to February 26, 1996, both area codes (615 and 423) can be used. Beginning February 26, 1996, all calls to East Tennessee must use the 423 area code; calls made to 615 will then be routed to Middle Tennessee exchanges.

This period should provide enough time for the customer to make all necessary changes. Remember, this will require that you change all autodial setups (modems, faxes, automatic dialers, speed calling, pagers, and cellular phones) for numbers dialed within this region. Some of our clients have experienced problems with using the 423 area code from their calling exchange. You may use 615 until February 26. In the meantime you need to be aware that your local phone company must be notified of the problem you are having so it can be fixed before February 26.

CHANGES TO THE COMPUTER CODE COLLECTION

One new code system was added to the computer code collection during the month.

CCC-641/NESTLE 5.0

OP SYS: UNIX

Language: Fortran 77

Computers: workstations

Format: tar

North Carolina State University, Raleigh, North Carolina, through the Energy Science Technology Software Center, Oak Ridge, Tennessee contributed this code system which solves the few-group neutron diffusion equation utilizing the nodal expansion method (NEM). NESTLE can solve eigenvalue (criticality), eigenvalue adjoint, external fixed-source steady-state, and external fixed-source or eigenvalue initiated transient problems. The eigenvalue problem allows criticality searches to be completed, and the external fixed-source steady-state problem can search to achieve a specified power level. Transient problems model delayed neutrons via precursor groups. Several core properties can be input as time dependent. Two- or four-energy groups can be utilized, with all energy groups being thermal groups (i.e., upscatter exits) if desired. Core geometries modeled include Cartesian and hexagonal. Three-, two-, and one-dimensional models can be utilized with various symmetries. Thermal conditions predicted by the thermal-hydraulic model of the core are used to correct cross sections for temperature and density effects. Cross sections are parameterized by color, control rod state (i.e., in or out), and burnup, allowing fuel depletion to be modeled. Either a macroscopic or microscopic model may be employed. All cross sections are expressed in terms of a Taylor's series expansion in coolant density, coolant temperature, effective fuel temperature, and soluble poison number density.

NESTLE is written in Fortran 77 and runs on Unix workstations with at least 16 megabytes of memory.It has been tested on IBM RS/6000 running AIX, HP9000/700 running HPUX, DEC5000 running Ultrix, and SUN OS platforms. Three DS/HD 3.5-in. (1.44 Mb) DOS diskettes are used to transmit Unix compressed tar files containing the source code, makefiles, test problem input/output, electronic dictionary and database. Reference: EGG-NRE-11406 (June 1994).Unix Workstations; Fortran 77 (C00641/MNYWS/00).

CHANGE TO THE DATA LIBRARY COLLECTION

A new data library was added to the collection as a result of a foreign contribution.

DLC-187/HILO86R

OP SYS: all

Language: Fortran 77

Computers: all

Format: dos

Japan Atomic Energy Research Institute, Tokai-mura, Naka-gun, Japan, contributed this cross-section library for multigroup transport calculations for neutron and photon energies up to 400 MeV and 20 MeV, respectively. HILO86R is an upgrade of a similar library, DLC-119, in which neutron data below 19.6 MeV are derived from DLC-113/VITAMIN-E (ENDF/B-V) except for sulfur and lead. In HILO86R only the cross sections below 19.6 MeV were replaced with data processed from the JENDL-3 microscopic cross section library. Self-shielding factors are used to produce effective cross sections for neutrons less than 19.6 MeV considering rather coarse energy meshes. Neutron cross sections of 37 energy groups less than 19.6 MeV were collapsed from the 295-neutron JSSTDL library based on JENDL3, considering self-shielding factors. Above that energy, differential elastic cross section data have been chosen so that the total, i.e., elastic + nonelastic, cross sections agree with experimental data. Photon cross sections were also condensed from the JSSTDL library using a flat weighting spectrum while secondary gamma-ray production cross sections did not change from those in HILO86. The library is P5. Data are provided for:

H, C, N, O, Mg, Al, Si, K, Ca, Fe, Pb.

BCBN will convert the data in ANISN format from card image to binary form. The package is transmitted on one DS/HD 3.5-in. (1.44 MB) DOS diskette which contains the cross sections, the BCD to binary conversion program, and input for the BCD-binary program in BCD card images. Reference: JAERI-M 93-020 (1993). ASCII card images; All computers (D00187/ALLCP/00).

CONFERENCES, COURSES, SYMPOSIA

RSIC attempts to keep its users/contributors advised of conferences, courses, and symposia in the field of radiation protection, transport, and shielding through this section of the newsletter. Should you be involved in the planning/organization of such events, feel free to send your announcements and calls for papers to RSIC.

International Conference on Radiation and Health

The effects of 'low dose exposure' to population groups has been a matter of concern for many years. In the period 1991- 95 about 600,000 persons from the former Soviet Union emigrated to Israel. Of this number, about 120,000 came from the Ukraine, Belarus and Russia from areas that were contaminated with varying levels of radioisotopes. This group in Israel is one of the largest outside the Commonwealth of Independent States from these areas and certainly is the most assessable, as well as being positively motivated for clinical assessments. Study results from this group are now being obtained.

In order best to associate these findings with other research on health and radiation, a conference has been planned with the objective of bringing together groups whose work relates to the effects of radiation on populations and to discuss the application of relevant advances in molecular and cellular biology, oncology, genetics, nuclear medicine, epidemiology, psychosociology and health physics.

The conference will be held in Beer Sheva, Capital of the Negev, at the Ben Gurion University of the Negev in Israel in November 3-7, 1996. An interesting program of social events including receptions and outings, etc, is planned with a special program for accompanying persons and children.

Papers in any of the following areas will be welcomed:

1. Physics and health physics: Radioisotope methodology, whole body counting, ground contamination, ESR, population dosimetry modeling, low level isotope measurements.

2. Molecular biology: Determination of DNA effects and alterations of genome, oncogene expression, methodologies, storage of tissues for possible future technologies.

3. Biological indicators of exposure: Cytogenetics, chromosome painting, clastogenic factors, micronuclei, Glycophorin A, HPRT, indices of oxygen radical toxicity, etc.

4. Long term effects: Carcinogenic: Early indicators, leukemia, thyroid , detection, other.

Genetic: Mutation detection and incidence, methodologies, role in carcinogenic effects.

Non-malignant: Hypertension, asthma, autoimmune, thyroid functional changes, other.

5. Nuclear Medicine and Biology: Metabolism of radioisotopes at cell, tissue and whole body level, detection in vivo.

6. Epidemiology: Evaluating population impact and assuring in ongoing operations that health problems are looked for in a monitoring program which can lead to effective intervention. Interaction of radiation and other environmental agents, industrial and work-place exposures.

7. Psychosocial: Counseling, post stress syndromes, evaluation of impact, referral methodologies for prevention of stigmatization.

8. Risk assessment: Due to radioisotopes of different kinds, non-ionizing radiations, population subgroups at higher risk than most of the population epidemiological and experimental data for extrapolation, as used to support regulations.

9. Long term assessment and follow-up: Direction of future studies, methodology for optimal follow-up data collection. Cooperation and collaboration between working groups.

Please contact the Secretariat if you wish to be placed on the mailing list, and indicate if you wish to present a paper with a preliminary title.
