A Brief Note On The Therac 25 Incident

Each of the experiments used different dosimetry devices to detect the amount of radiation exposure. By using these devices not only does it measure how much radiation exposure patients are being exposed to but also the amount of radiation the technicians are being exposed to. Using different dosimeters helps predict which ones pick up more and less radiation. Dental radiology technicians should wear the dosimeter badges while working, so they can be measured at all times. By measuring the amount of scatter radiation in multiple ways helps us regulate the

Paradise Hills Medical Center’s radiation department, made a radiation overdose on 22 oncology patients. The error was attributed to a flaw in the radiation equipment

It is not uncommon for a company to want to shell out their newest and latest machine as quick as possible, but along with this comes the temptations to cut corners and possibly make mistakes. The Therac-25 case is a famous example of this. The Therac-25 was originally developed in 1976 by the Atomic Energy of Canada and CGR, a French Based Company (Nielsen, 2003). The Therac-25 was a multi-million dollar radiation therapy

The FDA also watches certain electrical devices to make sure that they do not give off adverse amounts of radiation. Examples of equipment that fall under its jurisdiction are radiation safety performance standards for microwave ovens, television receivers, diagnostic x-ray equipment, cabinet x-ray systems (such as baggage x-rays at airports), laser products, ultrasonic therapy equipment, mercury vapor lamps, and sunlamps. They are also in charge of going to mammography facilities and inspecting them.

I'm investigating an incident occurred on Nov 11, 2015, at Modells store 1518 Benning Rd NE, Washington, DC. One of employee, Mr. Stuart Anderson was assaulted by an individual. I'm trying to ascertain if there is digital video footage on the day of the incident, Nov 11, 2015 between 2:50pm -

EREPORT # 19310 stated the following: The incident happened thursday and friday of last week. Mekoveonna (Anna) has been whipped many times by her mother's husband. Most recently, on Friday night was the worst of any of them. Mom's husband took a belt and struck her more times than she was able to recall or that her sister (Shay) could recall. At one point during him whipping her, she fell to the ground trying to get away and he then struck her across the face with the belt and continued whipping her even though she was yelling that he hit her face numerous times. After he finished, her mom then whipped her as well. Her sister, Shakoveonce (Shay) is physically handicapped and expressed that her mother has whipped her with a belt, but not as

This note is very important, because radiation is a very dangerous thing and you have to make sure you know the steps and for what you’re doing. Never take a risk.

Spencer Kenley Mrs. Efaw American Literature, P5 29 January 2018 The Effect of the Space Shuttle Challenger Disaster The Challenger malfunctioned on January 28, 1986, at 11:38 AM. The temperature was thirty-six degrees Fahrenheit in Cape Canaveral, Florida, and after seventy-three seconds of flight, the O-rings failed and the Challenger exploded into a giant cloud in the sky. All seven astronauts died, including Christa McAuliffe, a teacher in Concord, New Hampshire, chosen by the National Aeronautics and Space Administration from thousands of applicants to go into space and preform school lessons.

The devised code of ethics plays a vital role in the deciding factor for the engineers. Thus, in the case of the Gee-Whiz Mark 2 (GWM2) having evidence that 25,000 units are not compliant with safety standards in North America or Europe shows that the public's security is in jeopardy. Complying to the first fundamental canon of the NSPE code of ethics for engineers states that, "engineers shall hold paramount the safety, health, and welfare of the public”. Sadly to say, the current products only put users at a much higher risk of electrocution and death. Thus, by the virtue of the fundamental canon, engineers at Gee-Whiz Mark 2 morally cannot distribute detrimental products to the public in any geographic location, even if the law permits. Taking Toyota Motors in 2009 as an example, where more than 680,000 vehicles were recalled in the United States alone, due to safety concerns of the airbags and the brake lights being defective (Valdes-Dapena, 2012 ). Even though this company could have disregarded the issue and continue to sell defective machines, they instead did what was morally right for the citizens and recalled the products. A product recall of thousands of units is not easy for any company, resulting in a multi-billion financial loss and the expenditure of sales time. Nonetheless, when someone’s life is at stake there is no choice but to resolve the emerged problem, no matter the loss that will be incurred by the

The Challenger has had a total of 10 space missions. Including the Challenger Tragedy. The first ship was the STS-6 spaceship. It was launched on April 4, 1983. The mission was to deploy the first Tracking and Data Relay Satellite (TDRS) into orbit. There were 4 people on that spaceship. Their names were Paul J. Weitz, Karol J. Bobko, F. Story Musgrane, and Donald H. Peterson. They landed on April 9, 1983.

A family hailing from Bnei Brak was returning from a Bein Hazmanim outing, when they were involved in a fatal four car collision. Their little boy, 3.5 yeard old, tragically lost his life in the horrific crash, which happened at the Sira Junction. A toddler and the mother are in moderate condition and the father is in fair condition in Ichilov Medical Center.

Brown was fatally shot by police officer Darren Wilson at 12:03pm, Brown reportedly held his hands up in surrender, yet the unarmed teenager was still shot dead in the streets in an unlawful killing by a criminal justice representative. Within moments of the incident social media was updated and the world had been alerted. “I just saw someone die,” was posted on Twitter followed by the photo of lifeless Brown creating local concern and hunger for information as to why the young man was gunned down unlawfully when his body was still and remained in a position that told the officer that he was unarmed and in a plead for him not to shoot. Michael Brown was murdered in August of 2014 and sadly he was one of many unarmed black men that were

These six accidents began 3 June 1985 with a sixty-one year old woman receiving her twelfth treatment at Kennestone Regional Oncology Center in Marietta, Georgia. She had her breast removed and lost the use of a shoulder and arm after feeling a “tremendous rush of heat and red-hot sensation”, while receiving follow-up treatment for a malignant tumor removed from her breast in that facility (Porrelo, A.). The second accident occurred at the Ontario Cancer Foundation clinic in Canada on 26 July 1985 where a forty-year-old patient was in receipt of her twenty-fourth Therac-25 treatment. During the treatment, the machine issued an "H-tilt" error message. This prompted the

With a new source donor on the hook, it was now time to invest some time in figuring out what happened to the Kimko incident. In trying to put a stopping in her current problem coming back, and to not jeopardize the business, she would have to determine how it happened, how did the infection get by her precautions. She needed to determine if the infection was donor based, process based, or some new unforeseen issue the research had not identified. If she did not get to the bottom of this and quickly, her underground livelihood was fucked, not to mention a lot of pissed of clients and the possibility of federal prison time if discovered. The logical place to start is to try and get an autopsy report on the donor to identify the infection

In terms of education, enormous equipment and expensive yet high quality machines have always surrounded the College of Medical Radiation Technology (or CMRT). However, it is not just about the cost but also about their effectiveness and usefulness for the CMRT students. With these machines, students get to have hands-on activities that prepare them for when they take their internship in hospitals and as future health
