OVERVIEW

Radiation protection technicians monitor radiation levels, protect workers, & decontaminate radioactive areas. They work under the supervision of nuclear scientists, engineers, or power plant managers & are trained in the applications of nuclear & radiation physics to detect, measure, & identify different kinds of nuclear radiation. They know federal regulations & permissible levels of radiation.

HISTORY

All forms of energy have the potential to endanger life & property. This potential existed with the most primitive uses of fire, & it exists in the applications of nuclear power. Special care must be taken to prevent uncontrolled radiation in & around nuclear power plants. Skilled nuclear power plant technicians are among the workers who monitor & control radiation levels.

Around 1900, scientists discovered that certain elements give off invisible rays of energy. These elements are said to be radioactive, which means that they emit radiation. Antoine-Henri Becquerel, Marie Curie, & Pierre Curie discovered & described chemical radiation before the turn of the century. In 1910, Marie Curie isolated pure radium, the most radioactive natural element, & in 1911 she was awarded the Nobel Prize for chemistry for her work related to radiation.

Scientists eventually came to understand that radiation has existed in nature since the beginning of time, not only in specific elements on Earth, such as uranium, but also in the form of cosmic rays from outer space. All parts of the Earth are constantly bombarded by a certain background level of radiation, which is considered normal or tolerable.

During the 20th century, research into the nature of radiation led to many controlled applications of radioactivity, ranging from X rays to nuclear weapons. One of the most significant of these applications, which has impacted our everyday life, is the use of nuclear fuel to pro duce energy. Nuclear power reactors produce heat that's used to generate electricity.

Scientists are still trying to understand the biological effects of radiation exposure, but we know that short-term effects include nausea, hemorrhaging, & fatigue; long-range & more dangerous effects include cancer, lowered fertility, & possible birth defects. These factors have made it absolutely clear that if radiation energy is to be used for any purpose, the entire process must be controlled. Thus, appropriate methods of radiation protection & monitoring have been developed. The radiation protection technician’s job is to ensure that these methods are employed accurately & consistently.

THE JOB

Radiation protection technicians protect workers, the general public, & the environment from overexposure to radiation. Many of their activities are highly technical in nature: they measure radiation & radioactivity levels in work areas & in the environment by collecting samples of air, water, soil, plants, & other materials; they record test results & inform the appropriate personnel when tests reveal deviations from acceptable levels; they help power plant workers set up equipment that automatically monitors processes within the plant & records deviations from established radiation limits; & they calibrate & maintain such equipment using hand tools.

Radiation protection technicians work efficiently with people of different technical backgrounds. They instruct operations personnel in making the necessary adjustments to correct problems such as excessive radiation levels, discharges of radionuclide materials above acceptable levels, or improper chemical levels. They also prepare reports for supervisory & regulatory agencies.

Radiation protection technicians are concerned with ionizing radiation, particularly three types known by the Greek words alpha, beta, & gamma. Ionization occurs when atoms split & produce charged particles. If these particles strike the cells in the body, they cause damage by upsetting well-ordered chemical processes.

In addition to understanding the nature & effects of radiation, technicians working in nuclear power plants understand the principles of nuclear power plant systems. They have a thorough knowledge of the instrumentation that's used to monitor radiation in every part of the plant & its immediate surroundings. They also play an important role in educating other workers about radiation monitoring & control.

Radiation protection technicians deal with three basic radiation concepts: time, distance from the radiation source, & shielding. When considering time, technicians know that certain radioactive materials break down into stable elements in a matter of days or even minutes. Other materials, however, continue to emit radioactive particles for thousands of years. Radiation becomes less intense in pro portion to its distance from the source, so distance is an important concept in controlling radiation exposure. Shielding is used to protect people from radiation exposure. Appropriate materials with a specific thickness must be used to block emission of radioactive particles.

Because radiation generally can't be seen, heard, or felt, radiation protection technicians use special instruments to detect & measure it & to determine the extent of radiation exposure. Technicians use devices that measure the ionizing effect of radiation on matter to determine the presence of radiation & , depending on the instrument used, the degree of radiation danger in a given situation.

Two such devices are Geiger counters & dosimeters, which measure received radiation doses. Dosimeters are often in the form of photographic badges worn by personnel & visitors. These badges are able to detect radioactivity because it shows up on photographic film. Radiation protection technicians calculate the amount of time that personnel may work safely in contaminated areas, considering maximum radiation exposure limits & the radiation level in the particular area. They also use specialized equipment to detect & analyze radiation levels & chemical imbalances.

Finally, although the radiation that's released into the environment surrounding a nuclear facility is generally far less than that released through background radiation sources, radiation protection technicians must be prepared to monitor people & environments during abnormal situations & emergencies.

Successful technicians are usually individuals who are able to confidently accept responsibility, communicate effectively in person & on paper, & enjoy doing precise work. Their participation is vital to the successful application of nuclear technology.

Federal security clearances are required for workers in jobs that involve national security. Nuclear Regulatory Commission (NRC) clearance is required for both government & private industry employees in securing related positions. Certain projects may necessitate military clearance with or without NRC clearance. Employers usually help arrange such clearances.

EXPLORING

Ask your school counselor to help you learn more about this occupation. You also can obtain information from the occupational information centers at community & technical colleges.

Your science teacher may be able to arrange field trips & invite speakers to describe various careers. Nuclear reactor facilities are unlikely to provide tours, but they may be able to furnish literature on radiation physics & radiation control. Radiation protection technicians employed at nuclear-related facilities may be invited to speak about their chosen field.

Radiation is used for medical diagnosis & treatment in hospitals all over the country. Radiology departments of local hospitals often provide speakers for science or career classes.

In addition, a utilities company with a nuclear-fired plant may be able to offer you a tour of the visitor’s center at the plant, where much interesting & valuable information about nuclear power plant operation is available. Small reactors used for experiments, usually affiliated with universities & research centers, also may give tours.

EMPLOYERS

Radiation protection technicians are employed by government agencies, such as the Department of Energy & the Department of Defense, as well as electric power utilities that operate nuclear plants. Other than utilities, technicians are employed by nuclear materials handling & processing facilities, regulatory agencies, nondestructive testing firms, radiopharmaceutical industries, nuclear waste handling facilities, nuclear service firms, & national research laboratories.

STARTING OUT

The best way to enter this career is to graduate from a radiation control technology program & make use of the school’s placement office to find that first job. Another excellent way to enter the career is to join the U.S. Navy & enter its technical training program for various nuclear specialties.

Graduates of radiation control technology programs are usually interviewed & recruited while in school by representatives of companies with nuclear facilities. At that time, they may be hired with arrangements made to begin work soon after graduation. Graduates from strong programs may receive several attractive job offers.

Entry-level jobs for graduate radiation protection technicians include the position of radiation monitor. This position involves working in personnel monitoring, decontamination, & area monitoring & reporting. Another entry-level job is instrument calibration technician. These technicians test instrument reliability, maintain standard sources, & adjust & calibrate instruments. Accelerator safety technicians evaluate nuclear accelerator operating procedures & shielding to ensure personnel safety. Radiobiology technicians test the external & internal effects of radiation in plants & animals, collect data on facilities where potential human expo sure to radiation exists, & recommend improvements in techniques or facilities.

Hot-cell operators conduct experimental design & performance tests involving materials of very high radioactivity. Environmental survey technicians gather & prepare radioactive samples from air, water, & food specimens. They may handle nonradioactive test specimens for test comparisons with National Environmental Policy Act standards. Reactor safety technicians study personnel safety through the analysis of reactor procedures & shielding & through analysis of radioactivity tests.

ADVANCEMENT

A variety of positions are available for experienced & well-trained radiation protection technicians. Research technicians develop new ideas & techniques in the radiation & nuclear field. Instrument design technicians design & prepare specifications & tests for use in advanced radiation instrumentation. Customer service specialists work in sales, installation, modification, & maintenance of customers’ radiation control equipment. Radiochemistry technicians prepare & analyze new & old compounds, utilizing the latest equipment & techniques. Health physics technicians train new radiation monitors, analyze existing procedures, & conduct tests of experimental design & radiation safety. Soils evaluation technicians assess soil density, radioactivity, & moisture content to deter mine sources of unusually high levels of radioactivity. Radioactive waste analysts develop waste disposal techniques, inventory stored waste, & prepare waste for disposal.

Some of the most attractive opportunities for experienced radiation protection technicians include working as radiation experts for a company or laboratory, or acting as consultants. Consultants may work for nuclear engineering or nuclear industry consulting firms or manage their own consulting businesses.

EARNINGS

The earnings of radiation protection technicians who are beginning their careers depend on what radiation safety program they work in (nuclear power, federal or state agencies, research laboratories, medical facilities, etc.). They may begin as salaried staff or be paid hourly wages. Technicians who receive hourly wages usually work in shifts & receive premium pay for overtime.

The U.S. Department of Labor reports that median hourly earnings of hazardous materials removal workers (including radiation protection technicians) were $13.71 in 2000. Wages ranged from less than $9.33 per hour to more than $24.01 per hour or $19,410 to $49,950 a year.

Most trained technicians earn annual starting salaries of up to $25,000 a year. After three to five years of experience, they can expect to earn as much as $33,000 a year. Consultants may earn as much as $42,000 a year. Earnings are affected by whether technicians remain in their entry-level jobs or become supervisors & whether they become registered radiation protection technologists.

Technicians usually receive benefits, such as paid holidays & vacations, insurance plans, & retirement plans. Because of the rapid changes that occur in the radiation safety industry, many employers pay for job-related study & participation in workshops, seminars, & conferences.

WORK ENVIRONMENT

Depending on the employer, work environments vary from offices & control rooms to relatively cramped & cold areas of power plants.

Of all power plant employees, radiation protection technicians are perhaps best able to evaluate & protect against the radiation hazards that are an occupational risk of this field. The safety of all plant workers depends on the quality & accuracy of their work.

Radiation protection technicians wear film badges or carry pock et monitors to measure their exposure to radiation. Like all other nuclear power plant employees, technicians wear safety clothing, & radiation-resistant clothing may be required in some areas. This type of clothing contains materials that reduce the level of radiation before it reaches the human body.

In some of the work done by radiation protection technicians, radiation shielding materials, such as lead & concrete, are used to enclose radioactive materials while the technician manipulates these materials from outside the contaminated area. These procedures are called hot- cell operations. In some areas, automatic alarm systems are used to warn of radiation hazards so that proper protection can be maintained.

OUTLOOK

There are 103 nuclear power plants licensed to operate in 32 states of the United States. In an effort to offset the effects of rising costs to the public for energy obtained from traditional resources, some government officials are calling for the construction of new nuclear power plants & the re-licensing of existing ones. If these plants are constructed & existing plants are re-licensed, radiation protection technicians will enjoy increased employment opportunities.

However, even if the nuclear power industry experiences a decline, the employment outlook for radiation protection technicians should remain strong. Technicians are needed to support radiation safety programs in Department of Energy facilities, Department of Defense facilities, hospitals, universities, state regulatory programs, federal regulatory agencies, & many industrial activities. New technicians will be needed to replace retiring technicians or technicians who leave the field for other reasons. Increased efforts to enforce & improve safety standards may also result in new jobs for technicians.

Because radiation programs have been in development for half a century, most of the radiation safety programs are well-established & rely primarily on technicians to keep them running.
