- The biological effects of UV radiation do not appear readily, so individuals who are often overexposed become aware of the damaging effects and the extent of damage over time. If exposure is sufficiently high, systematic effects such as nausea, fever and malaise may transpire. In cases of tremendous exposure, premalignant or malignant changes may ensue (2). Moreover, skin cancer, cataracts and immunosupression are the primary health effects associated with UV-B radiation exposure (3).

Helena Modjeska Helena Modjeska (October 12, 1840 – April 8, 1909), whose actual Polish surname was Modrzejewska (Polish pronunciation: ), was a renowned actress who specialized in Shakespearean and tragic roles. Early life Helena Modjeska was born in Kraków, Poland, on October 12, 1840.[1] [2] Her name was recorded at birth as Jadwiga Benda, but she was later baptized Helena Opid, being given her godfather’s surname.[1] Modrzejewska as Barbara Radziwiłłówna, 1865 The question of her origins is a complicated one.

Radiation Quantities and Units Equivalent dose - The biological effects of an absorbed dose of a given magnitude are dependent on the type of radiation delivering the energy (i.e., whether the radiation is from x rays, gamma rays, electrons (beta rays), alpha particles, neutrons, or other particulate radiation) and the amount of radiation absorbed.

Radiation and Health Alpha particles, beta particles, x-rays and gamma rays are forms of ionizing radiation. On the other hand, radiation that is not capable of producing ions in matter is known as nonionizing radiation. Radiowaves, microwaves, heat waves, visible light and ultraviolet radiation are forms of nonionizing radiation. This booklet focuses on the health effects of ionizing radiation.

Ionizing radiation Gamma rays, X-rays, and the higher ultraviolet part of the electromagnetic spectrum are ionizing, whereas the lower ultraviolet part of the electromagnetic spectrum, visible light (including nearly all types of laser light), infrared, microwaves, and radio waves are considered non-ionizing radiation.edical procedures, such as diagnostic X-rays, nuclear medicine, and radiation therapy are by far the most significant source of human-made radiation exposure to the general public. Some of the major radionuclides used are I-131, Tc-99, Co-60, Ir-192, and Cs-137.

Biological Effects of Radiation Ionizing radiation is radiation with enough energy so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized. Ionizing radiation has enough energy to electrically charge or ionize matter. The cells in living organisms are also made of matter, so they too can be ionized. Cosmic rays, x-rays, gamma rays, alpha particles and beta particles are forms of ionizing radiation. Ionizing radiation may come from a natural source such as the Sun or it may come from a man-made source such as an x-ray machine.

Radiation Effect on Life Genetic Effects. Genetic information for the production and function of a new organ is contained in the chromosomes of germ cells-sperm and ovum. In reality, genetic effects are due to the damages to DNA molecules. Normal human somatic cells contain 46 chromosomes.omatic Effects. Radiation affects rates of cell division. Hastening and slowing down cell division affect embryonic tissues. Damages to cell membranes, mitochondria and cell nuclei result in abnormal cell functions, affecting their division, growth and death.

Radiation Effect on Life Radiation effects are divided into somatic effects and genetic effects. The former affects the function of cells and organs, whereas the latter affects the future generations.omatic Effects. Radiation affects rates of cell division. Hastening and slowing down cell division affect embryonic tissues. Damages to cell membranes, mitochondria and cell nuclei result in abnormal cell functions, affecting their division, growth and death.

Radon BIOLOGICAL EFFECTS OF IONIZING RADIATION. Ionizing radiation in very high levels is known to increase the incidence of cancer, birth. anomalies, erythema, and other problems. In low levels, these effects are either very, very small. compared to natural incidences or non-existent depending on the biological model used for. estimating the potential risk.
