Both have been exposed to low life-time doses of radiation although, in the atomic bomb, people received their entire dose in a matter of seconds. This data reflects risk associated with external, whole body radiation doses. Cytogenetic abnormalities can be observed at doses as low as mGy but there may be non-detectable damage at lower doses which is able to cause cancer in some individuals. Because cancer also occurs in people without excess exposure to radiation, the increase in risk resulting from irradiation is described in relative terms.

The excess relative risk ERR is the ratio of the extra cases cancer observed in people exposed to radiation compared to the cases observed in people not exposed to additional radiation. This study estimated the excess relative risk EER of developing solid cancers as between 0. A person exposed to a dose of mSv would, for example, have an ERR of 0.

An analysis of several large studies which have examined the risk of cancer in nuclear workers estimated the ERR for all solid tumours as 0. A person with an excess in relative risk ERR of 0.

Clinical Manifestations of Chronic Radiation Syndrome

This would mean that a population of people exposed to mSv of radiation might expect an increase from cancers to cancers over the life of this population. Communication of risk In most radiological incidents the majority of people are likely to be exposed to doses which do not cause immediate and severe physical effects. Although moderate and low doses of radiation can cause illness in some people, there are limited options for intervening to reduce this risk once irradiation has occurred.

The main objective in most people is, therefore, to manage the psychological consequences of this risk and effective communication is a key aspect of this. Providing information about the magnitude and severity of health risks will help reduce distress and the inappropriate use of medical interventions which are potentially harmful. If mass casualties occur then managing the anxiety of people is particularly important to allow triage for appropriate management and prevent medical facilities being overwhelmed.

The general objectives of risk communication are: To engender understanding of the probability and nature of adverse health effects faced by the person. To produce an understanding of the limitations of medical intervention in reducing this risk. To reduce psychological distress by engendering trust in the validity of the risk assessment. Reduction of risk The only way to reduce the health risks which result from irradiation is to minimise the total dose of radiation a person receives.

Depending on the situation this can be achieved by a range of means: Evacuation from a contaminated site, terminating ongoing exposure Providing sheltering to reducing contact with radioactive material or exposure to radiation Surface decontamination removal of clothes, washing to remove radioactive material Internal decontamination to increase the rate at which radionuclides are removed from the body, or block their uptake into the body The aim of risk reduction measures is to achieve an acceptable level of risk, not eliminate the risk from radiation entirely.

What is reasonably achievable depends on the availability of facilities for removing people from a contaminated site and providing decontamination. It is also reasonable to accept a higher dose of radiation if this is necessary to achieve a reduction in other risks faced by the person.

In people who have suffered trauma in an explosion, for example, complete decontamination may be a lower priority than preventing death from these injuries. Similarly, the health risks posed by some medicines, such as DTPA, used for internal decontamination may exceed the risks from low-level radiation exposure. In defining ALARA it is useful to consider how this has been applied to the public or those working with radiation. An average exposure of 1 mSv per year is considered an acceptable risk for the general public and reflects environmental exposure to radiation.

This may be exceeded in some years provided the 5 year average is 1mSv. Appendix D: Selected Radionuclides. Document download This publication is available as a downloadable document.

    However, when humans are exposed to very large amounts of ionizing radiation in a short period of time, Acute Radiation Syndrome ARS occurs. For context, a mammogram is only 0.

    Radiation sickness: Sources, effects, and protection

    People exposed to rads start to show signs of ARS , which include fatigue, nausea, vomiting, diarrhea, and seizures — and the higher the dose, the more likely death is to occur. Generally speaking, anything over rads is considered a lethal dose.

    Here are five of the most notable incidents. After an injury in , Byers was prescribed a tonic called Radithor in the hopes it would ease his pain and improve his health.

    Over the next two years, Byers guzzled an estimated 14, bottles of Radithor, causing his jaw, teeth, and parts of his skull to dissolve. After a protracted illness , Byers died of radiation sickness in March at the age of Internationally renowned chemist and physicist Marie Curie is famous for discovering the radioactive elements polonium and radium, along with being the first woman to snag the Nobel prize in physics and chemistry.
