Health Physics units

Exposure calculation to the emission calculations involving impact of emissions on humans and ecosystem of the emissions means the impact calculation of the dose from the increased concentration. The impact calculation is followed by calculation of impacts (damage in physical units) from this dose, using a dose-response function. The impact of WEEE substances on health and the environment is location specific and is based on conditional, that is to say the way the WEEE is taken care of. Hence, the exposure assessment relates to the population and the ecosystem being exposed to the externalities.

An SGS was used to segregate uranium-contaminated soil at the ER Site 16 Concrete Dump Site at the DOE s Sandia National Laboratories in Albuquerque, New Mexico. The actual cost of the full-scale remediation was 164,109, including 59,326 for mobilization, 57,770 for operations, and 47,013 for demobilization. Based on the 661.8 yd of soil processed, the unit cost of the operation was 236/yd. Site preparation, crane operation, oversight labor, health physics support, water supply, sample analysis, and waste disposal were not included in the actual or unit costs (D21040S, p. 74 D21233Z, pp. 12, 13). 

During World War II, a different exposure situation was created in the United States by the Manhattan Project. Several hundreds of thousands of workers were recruited to a new industry in remote and secret locations. Since some of the hazards of working with radiation were recognized in advance, workers at many sites were monitored for radiation exposure. A new discipline. Health Physics, was created to provide radiological protection. The systematic collection of dosimetry records created an opportunity to investigate relationships between repeated exposure to small doses of radiation and disease.

Ordnance and Supply Units. Explosive Ordnance Detachments normally handle or coordinate the removal of all unexploded ordnance. The Industrial Operations Command (IOC) assists in the removal, storage and processing of equipment from the battlefield. Preventive medicine units need to coordinate with both the maintenance companies and IOC to ensure proper health physics practices. The Army Materiel Command (AMC) is the Nuclear Regulatory Commission (NRC) license s holder for most of the radioactive items in the field. 

B. Preventive Medicine Detachment. This detachment provides technical consultation support on preventive medicine issues throughout its area of responsibility. The unit provides specialized support in the areas of disease and non-battle injuries (DNBI) surveillance, health physics, disease vector identification, environmental engineering, health threat profile, and health hazard assessment. Its medical NBC capabilities may include but are not limited to ... 

Since improperly handled radiation may produce deleterious effects to humans, it is important that individuals who use radiation sources learn the fundamentals of dosimetry, definition of dose units, biological effects of radiation, standards for radiation protection, and operation of health physics instruments. This chapter briefly discusses all these items. If more detailed treatment of these topics is needed, consult the bibliography and references given at the end of the chapter. 

Chapter 15 is devoted to activation analysis, a field with wide-ranging applications. Health physics is discussed in Chap. 16. I feel that every person who handles radiation should know at least something about the effects of radiation, radiation units, and regulations related to radiation protection. This chapter may be omitted if the reader has already studied the subject. 

For the two-unit plants in the UK (Magnox or AGR) with one control room, the normal complement of staff for one shift is illustrated in Fig. 7.1. In addition, there are industrial staff, e.g. two Operations Foremen and one Health Physics Monitor Foreman, who supervise about 20 persons of a non-academic qualification level, defined as skilled plant operators and semi-skilled plant attendants . 

A good summary of the status of radioactive waste disposal in tiie United States can be found in an article by John R. Vincenti, Low-Level Radioactive Waste Disposal in the United States in the Supplement to tiie Health Physics Journal, Vol. 76, No. 5, May 1999. It is noted in tiiis article tiiat the volume of tiiis type of waste has decreased from 3.8 million in 1990 to 0.32 milhon in 1997.

For larger organizations, the safety and health units in the staff structure may include several specialists. There may be specialists in safety, industrial hygiene, health physics, occupational medicine and nursing, and fire protection. Many organizations have consolidated safety, health, and environmental responsibilities into one organizational unit. Sometimes security is part of this unit. Sometimes insurance...

Subcommittee on Nuclear Terminology and Units. This concise glossary provides brief definitions of nuclear terms, including nuclear and reactor physics, health physics, and regulatory terms. Also includes an appendix on a classification system for reactors. 

Processes to clean nuclear power-generating equipment can be considered specialized applications of the iron oxide and copper dissolution methods considered earlier in this book. However, because of the radioactivity usually present in deposits that foul nuclear generating equipment, speciaiized procedures have been developed to clean some types of nuclear equipment. Three different types of processes are conducted (1) chemicai treatments are used to decontaminate parts of the units to allow maintenance or before decommissioning the plant (these are health physics issues) ...

Definitions. Physical and chemical agents that combat pathogenic and nonpathogenic microorganisms are often referred to as disinfectants. Attempts to standardize terminology by health agencies in the United States, such as the CDC, the Pood and Dmg Administration (PDA), and the EPA, have resulted in the following definitions.
