Disability Benefits Insurance Under the unemployment insurance laws of the country, most workers are afforded some income protection during periods of unemployment However, to be eligible for these benefits the worker must be ready, willing, and able to work Therefore, he cannot receive these benefits if disabled If a disability arose out of the and dunng the course of his employment, he may be entitled to workmen's compensation benefits, but no protection extends to off-the-job disability except under laws in four states or as may be provided under private insurance plans or employee welfare plans Aside from compulsory plans in effect in the four states, an increasing number of em ployers in recent years have installed private plans that give their employees some in demnity for loss of time due to nonoccupational disability Such plans are completely voluntary on the part of the employer or are entered into as a result of collective bargain ing between employers and employees or their trade union Where such group disability plans are in effect, they, together with state unemploy ment and workmen's compensation laws, af ford the worker with some protection against such major threats to his income-producing power as inability to work because he is disabled on the job or off it Although there have been extensive dis cussions in most states concerning compul sory plans covering employees against nonoccupational illnesses and accidents, to date only four states have enacted such legisla tion These states are New York, New Jer sey, Rhode Island, and California In California and Rhode Island, the em ployee pays all the costs of such plans In New York and New Jersey, the employer and the employee share the costs Three of these four states treat this insurance as a function of unemployment Only one.

37--Industrial Hygiene Five basic safety factors Ionizing radiation can be a complex sub ject At the risk of over-simplifying some basic physical principles and ignoring others, the purpose of this chapter is to present enough information so the safety professional will realize the problems mvolved and know when to call upon radiation safety experts for help There are at least five basic factors that must be considered in such an approach to radiation safety Radioactive materials emit energy which can damage living tissue e There are five different lands of radio activity and there must be an understanding of their characteristics in order to recognize safety problems The types of ionizing radia tion with which we will be concerned are alpha, beta, X radiation (X ray), gamma, and neutrons Radioactive materials can be hazardous m two different ways Certain types can be hazardous even when located some distance away from the body These are external hazards Other types are hazardous only when they get inside the body by virtue of breathing, eating, or through broken skin These are referred to as internal hazards Tools are available for evaluating possible radiation hazards Meters or other devices are used for measuring radiation levels and estimating doses Specific guides and reference books Need for concern The first factor makes it necessary for peo ple to be concerned about ionizing radiation The fact that at the time of exposuie to ioniz ing radiation an individual is unable to sense the absorption of energy, with its related tissue damage, seems to give the hazard a mysterious qualitv which is frightening to some people This is unfortunate because many radioactive materials are far less hazardous to handle and use than is, for example, the family automo bile Nevertheless, radioactive materials emit en- 1060 Fic 37-9 --The penetrating power of alpha, beta, and gamma radiation Reprinted with permission from **Atomic Radiation*' <D 1957 by RCA Service Co, Inc ergy in the form of one or more of the five types of radiation noted previously This energy, when absorbed by living tissue, pro duces damage by a process called ionization To understand a little about ionization it is necessary to recall that the body is made up of vanous chemical compounds which are in turn composed of atoms Each atom has a nucleus with its own outer system of electrons When ionization occurs, some of the elec trons surrounding the atoms are forcibly ejected from their orbits The greater the exposure to ionizing radiation, the more elec trons displaced, and the more the physical damage to the cells containing the atoms that have lost electrons Incidentally, this is the reason why this type of radiation is referred to as "ionizing radiation " Light from the sun is very similar to X ray and gamma radiation, differing only m wave length and energy content (Fig 37-8) How ever, the sun's energy levels are too low to disturb orbital electrons and consequently light is not referred to as ionizing, even though it has enough energy to cause severe bums over a period of time The exact mechanism of the manner in which ionization affects body cells and tissue is complex However, just as with a moving automobile, radioactive matenals possess en-
