  • Arctic and sub-Arctic areas have become victims because reindeer feed on lichens that easily take up radioactive caesium-137, which is then passed on to humans through reindeer meat. (chernobylx.com)
  • How likely is strontium to cause cancer? (cdc.gov)
  • The International Agency for Research on Cancer (IARC) has determined that radioactive strontium is a human carcinogen. (cdc.gov)
  • Y-90 is becoming increasingly significant in medical treatments, specifically in cancer radiotherapy. (beatcancer.eu)
  • Scientific research involving Y-90 is pushing the boundaries of its potential in cancer treatment. (beatcancer.eu)
  • Zhu, R. For chest radiographs, images of patients ini- tially read as normal and later diagnosed with lung cancer showed that in approximately 90 of the cases, the cancer was visible on the chest image in retrospect [30]. (banglaforexacademy.com)
  • The group was involved in previously known "injection" and "ingestion" human-subject studies that exposed unwitting victims to radioactive material such as plutonium and strontium-90. (climate-connections.org)
  • There are tests to measure the level of strontium in blood, hair, feces, and urine. (cdc.gov)
  • The strontium and thallium content in major tissues, urine and faeces were estimated. (researchsquare.com)
  • Spirulina significantly reduced the whole body retention of strontium and thallium and enhanced their excretion through urine and faeces. (researchsquare.com)
  • Some of these radioactive nuclides have relatively short half-lives and have already decayed since the disaster occurred. (medicaltrend.org)
  • You can be exposed to radioactive strontium if you eat food that was grown in contaminated soil, or if you come near a source of radioactive strontium. (cdc.gov)
  • The Groves memo makes it clear that in 1943, U.S. scientists recommended using radioactive poison gas weapons in order to contaminate the air, water, soil, food, environment and the blood of exposed populations. (rense.com)
  • Exposure to stable or radioactive strontium occurs from ingesting contaminated food or drinking water or breathing contaminated air. (cdc.gov)
  • Food and drinking water are the largest sources of exposure to strontium. (cdc.gov)
  • We do not know if exposure to strontium will result in birth defects or other developmental effects in people. (cdc.gov)
  • How can families reduce the risk of exposure to strontium? (cdc.gov)
  • As a radioactive sample disintegrates, the number of decays per second decreases, but the fraction of nuclei that decay per second-the decay constant -does not change. (schoolbag.info)
  • Imagine that potassium-42 undergoes β - decay to form calcium-42. (schoolbag.info)
  • While N American coal reserves are large, coal used for producing electricity is the major source of GHG emissions and will need to be dramatically reduced by 85-90% before 2050. (theoildrum.com)
  • Radioactive caesium is also relatively rapidly transferred from feed to milk. (food-safety.com)
  • but, at a lower level, followed by strontium-90 and caesium-137 that will be present for decades to come. (chernobylx.com)
  • Caesium-137 and strontium-90 are being carried off to aquatic bodies through rain. (chernobylx.com)
