![]() ![]() Today it is being replaced by electron beam radiation therapy systems. When it decays to stable nickel, it emits two relatively high-energy gamma rays. In the medical field, the radioactive isotope Cobalt 60 has been used for radiotherapy to shrink tumors that will later be surgically removed, or to destroy cancer cells in inoperable tumors. Since half life is a constant, the ratio of carbon 14 to nitrogen 14 provides a measurement of the age of a sample. At the time of death organisms stop producing carbon 14. During beta decay, carbon 14 becomes nitrogen 14. It measures the time it takes for a given amount of the substance to become reduced by half as a consequence of decay, and therefore, the emission of radiation.Īrcheologists and geologists use half-life to date the age of organic objects in a process known as carbon dating. The half-life of a radioactive substance is a characteristic constant. N = 2 (remember (1/2) 2 = 1/4 and 1/4 = 0.It's a Question of Physics: What is meant by half-life? Half-Life Problem #10: How much time will be required for a sample of H-3 to lose 75% of its radioactivity? The half-life of tritium is 12.26 years. How much time will have elapsed when 5.00 grams remains?ĥ.00 / 100.0 = 0.05 (decimal fraction remaining) Problem #9: 100.0 grams of an isotope with a half-life of 36.0 hours is present at time zero. If the half-life is 23.9 hours, how much will be present at the end of one day? Two days? Seven days? Problem #8: At time zero, there are 10.0 grams of W-187. ![]() How much time will elapse for this sample to be considered gone? A radioactive sample is considered to be completely decayed after 10 half-lives. Problem #7: Fermium-253 has a half-life of 0.334 seconds. Problem #6: How long will it take for a 40.0 gram sample of I-131 (half-life = 8.040 days) to decay to 1/100 its original mass? N = 0.91254 (this is how many half-lives have elapsed) Solution: 17/32 = 0.53125 (this is the decimal amount that remains) Problem #5: A radioactive isotope decayed to 17/32 of its original mass after 60 minutes. Video: An Alternate Solution to the Above Problem What is the half-life of the sample?Ģ) How many half-lives must have elaspsed to get to 0.015625 remaining? Problem #4: After 24.0 days, 2.00 milligrams of an original 128.0 milligram sample remain. In addition, note that the question asked for the amount that decayed, not the amount that remaning. Note that the length of the half-life played no role in this calculation. How many grams of a 10.0 gram sample would have decayed after exactly three half-lives? Problem #3: Os-182 has a half-life of 21.5 hours. (1/2) 5.56 = 0.0213 (the decimal fraction remaining after 5.56 half-lives) Many of us had fallen in love with video games because of the phenomenological possibilities of the field and felt like the industry was reducing the experiences to least common denominators rather than exploring those possibilities. ![]() If one had 6.02 x 10 23 atoms at the start, how many atoms would be present after 20.0 days? Half-Life in many ways was a reactionary response to the trivialization of the experience of the first-person genre. Problem #2: Pd-100 has a half-life of 3.6 days. (1/2) 3 = 0.125 (the amount remaining after 3 half-lives) If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed? Problem #1: The half-life of Zn-71 is 2.4 minutes.

They also said that they would be willing to provide a universal decryptor for victims of the attack, but under the condition that they be paid $70,000,000 worth of BitCoin. REvil’s operators posted to their “Happy Blog” today, claiming that more than a million individual devices were infected by the malicious update. Spike in SophosLabs telemetry caused by REvil detections on July 2, 2021, showing hundreds of detections at its peak. In this particular outbreak, the REvil actors not only found a new vulnerability in Kaseya’s supply chain, but used a malware protection program as the delivery vehicle for the REvil ransomware code. Its affiliates have been exceedingly persistent in their efforts as of late, continuously working to subvert malware protection. And with the decline of several other RaaS offerings, REvil has become more active. Customers of managed service providers have been a target of REvil affiliates and other ransomware operators in the past, including a ransomware outbreak in 2019 (later attributed to REvil) that affected over 20 small local governments in Texas. REvil is a ransomware-as-a-service (RaaS), delivered by “affiliate” actor groups who are paid by the ransomware’s developers. Using an exploit of Kaseya’s VSA remote management service, the REvil actors launched a malicious update package that targeted customers of managed service providers and enterprise users of the on-site version of Kaseya’s VSA remote monitoring and management platform. Use this script to rollout an application by simply dropping it in your patch management file source for a given machine group and run the script on all required machines to install.On July 2, while many businesses had staff either already off or preparing for a long holiday weekend, an affiliate of the REvil ransomware group launched a widespread crypto-extortion gambit. The database variable call means I do not need to specify UNC paths, file source agent or credential, as it is dynamically retrieved. It will take those details and attempt to retrieve the installer on the fly from the configured Patch Management File Source and run with supplied switches on all machines you run it against. Today’s script will prompt you when run for an executable name for an install package and installation switches if needed (the method for that I’ll examine next time!). Simply refer to #vAgentConfiguration.agentTempDir# and there you have it! You’ll note in the above script I haven’t done this, for the sake of comparison.Īnd as hopefully all of my ‘Tip of the Day’s about scripting will have, you can download the XML script here to import into your Kaseya system. ![]() If you were not aware, looking through the product help file located within Kaseya you’ll find a chapter on Database Views that outlines the full extent of Views and Column Names you can retrieve with this same, simple method! Looking right back to example 1 above of the procedure variable #agentTemp#, you may not have realised you can do the same thing in one step using a database variable, instead of declaring the Agent Working Directory variable first. In fact, you can use this method to retrieve an extensive amount of information from the datbase, using the syntax #viewName.ColumnName#. As a result, I have no need to declare this variable at all. Where in the world is that coming from? And why is it not declared or created anywhere in the script? The neat thing is, this variable is drawing a piece of information directly from one of Kaseya’s inbuilt database views. So what exactly is a database variable? Well, reviewing the screenshot above of a complete script, note the use of the variable #vPatchConfiguration.FileSourceUNCPath#. File Source Installation Script using Database Variable ![]() |
