Therac-25 Radiation Treatment

Improved Essays
The Therac-25 machine was a third-generation machine produced by the company AECL which specialized in manufacturing machines which provided radiation therapy to cancer patients. This machine accomplished this by emitting a beam of electrons or x-rays to the cancerous area. This amount of radiation interferes with the cancerous tissue’s ability to grow by disabling the genetic material in the cell. However, since cancerous cells are not the only cells in the body that grow very quickly, skin and hair cells may also become affected by this radiation by causing the hair to fall out and leave lesions on the skin. Fortunately, these cells are usually able to make a full recovery a while after the radiation treatment is ended. AECL improved upon the Therac-25’s predecessors, Therac-6 and …show more content…
By having a “double pass” electron beam, the Therac-25 could produce much more energy in less amount of space than its predecessors. To put this into context, the normal dosage for an appointment of radiation treatment is around 200 rads (radiation absorbed dose). A dose of 500 rads exposed to the entire body will result in death 50% of the time. The …show more content…
The only part of which I slightly disagree with is that the “pre-market equivalence” route of approving an item into the market should have not have existed in the first place. I believe that if there are any “next-generation” machines or other items attempting to make their way onto the market, they should be subjected to the rigorous testing procedures conducted by the FDA. Even though the FDA did not have any sort of incidents with any devices before or recently afterwards, it could entice some companies to slack off on their safety procedures for updated machines, which could potentially put human lives at

    Medicine Changed by Radiation Radiation has changed over the years and wasn’t even known to be used in medicine until after it was used in the military in World War II. It was discovered by a German scientist but then the possibilities of all the things it could be used for was discovered by a Polish-born French scientist. Radiation changed medicine for the better by killing off cancerous, disease ridden germs and cells, this is significant because it changed the way we look at treatment. In 1895, radiation had just been discovered by Wilhelm Conrad Roentgen, a professor at Wuerzburg University in Germany. ("History of Radiography").…

    UVB Light Source and Irradiation of Mice The dorsal skin of mice was shaved using clippers before exposure to UVB radiation. UVB (200 mJ/cm2) was administered per day, three days per week, from a bank of four UVB lamps (Daavlin, UVA/UVB Research Irradiation Unit, Bryan, OH). The irradiation unit was equipped with an electronic controller to regulate UVB dosage at the fixed distance of 24 cm from the lamps to the dorsal skin surface of the mice. Wavelengths 1 mm in diameter, that persisted for at least 2 weeks, were defined as tumors and recorded.…

    Radiation therapy, the second method, requires the application of high energy X-rays to shrink the tumor and kill the malignant cells. The rays may be applied from an external machine or by placing the radiation source directly to the affected part of the body, by means of plastic tubes. Last treatment type is the chemotherapy whereby a combination of drugs is applied to kill the cancer cells. The drugs may be administered by mouth in the capsule form or may be applied intravenously via…

    In a paper published in July earlier this year, Dr. Patti Zettler, a professor of law at Georgia State University College of Law, listed strong reasons for the ability of the FDA to enact regulation within the existing regulatory framework. For any tDCS product to come under the jurisdiction of the FDA, it must first meet the requirements of a device under the FDA’s rules. This means that the device, “among other things, is intended for use in the cure, mitigation, treatment, or prevention of disease or to affect the structure or any function of the body”.10 Zettler argues in her paper that tDCS products can be categorized under the latter, as manufacturers’ “wellness and enhancement claims are generally claims that consumer tDCS products affect the structure or function of the body”.11 The latter category is one in which there is plenty of ambiguity, as it allows for the possibility of products such as exercise equipment to come under the jurisdiction of the FDA. However, historically, to combat this ambiguity, the FDA has exerted its regulatory power on products that “have a therapeutic connotation” when marketed with structure/function claims.12 With strong evidence, scholars are increasingly concerned that it is just a matter of “when”, not “if”, regulation will be brought to this industry. However, a larger problem…

It glowed in the night, it was presumed to cure cancer, it even was thought to give you eternal life, but for many innocent young girls in the 1920's, it was anything but wonderful and exquisite(Prisco). It was fatal.

    This can cause some very serious side effects; such as “heart damage, lung damage… and other cancers, such as leukemia.” Radiation sends “high energy beams, such as x-rays, to kill cancer cells.” The length of time that you receive radiation depends on how far along the cancer is and what stage you are on. Some rather serious risks of radiation are the symptoms “heart disease, stroke, thyroid problems… other forms of cancer, such as breast or lung cancer.” One last form of treatment is stem cell transplants.…

    This relies on a beam of high-energy particles, such as X-rays, directed at the cancer by a machine outside the body. The assault from this concentrated energy kills cells and reduces tumor size. Radiation therapy is often reserved for ALL involving the central nervous system or the testes, or for patients with T-cell disease. One more type of treatment is bone marrow and blood transplant. This consists of replacing diseased bone marrow with healthy blood and bone marrow.…

    Radiation therapy is relatively ineffective during certain phases of the cell cycle. The synergy of RFA and radiation therapy is likely due to cells which are radiosensitized by thermal therapy. Cells remain radiosensitized for up to 24 hours, therefore the efficiency of radiation therapy is increased during that window. This effect is summarized by Dewhirst et al in his review of the effects of thermal therapy [6]. The increased effectiveness of combining multiple modes of treatment is frequently time-dependent, as described for RFA and radiation therapy.…

Under circumstance of cutaneous wounds, damaged epidermis requires appropriate healing process to repair or regenerate skin functions. The skin homeostasis is sustained by skin somatic stem cells, which are localized within the basal layer (Fig. 1) of the skin epithelium and underlie the remarkable resilience of skin.

    Therac-25 Design Flaws

    The computer technology is a double edged weapon and this was the case in the therac-25 as its purpose was to treat patients, but as a result of the misuse of computer technology it harmed six innocent people. The problem with the design of the machine was that it was mainly controlled by its software and not its hardware. The programmer did not take into consideration that he was designing a machine that emits dangerous types of radiation that can be life threatening if they are not well controlled. One of the main reasons behind this design failure was because the designer preferred working alone to working in group which led to lots of software flaws.…
