This paper highlights carbon-14 for a number of reasons:</p><p>- Carbon-14 is radioactive and is released into air as <a href="https://kolektiva.social/tags/methane" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>methane</span></a> and <a href="https://kolektiva.social/tags/CO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CO2</span></a></p><p>- Before 2010, carbon-14 releases from nuclear reactors were virtually ignored in the United States. Today only estimates are required and only under certain restrictive circumstances.</p><p>- There is no good accounting of releases to date, so its impact on our health, our children’s health, and that of our<br><a href="https://kolektiva.social/tags/environment" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>environment</span></a> remains unknown, yet environmental measurement is possible, but can be challenging under certain<br>conditions. </p><p>- Carbon-14 has a half-life of over 5700 years and the element carbon is a basic building block for life on earth. Therefore, “it constitutes a potential health hazard, whose additional production by <a href="https://kolektiva.social/tags/anthropogenic" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>anthropogenic</span></a> sources of today will result in an increased <a href="https://kolektiva.social/tags/radiation" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>radiation</span></a> exposure to many future generations.”</p><p>- Like <a href="https://kolektiva.social/tags/tritium" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tritium</span></a>, it can collect in the tissues of the fetus at twice the concentration of the tissues in the mother, pointing to its<br>disproportionate impact on the most vulnerable human lifecycle: the developing child.</p><p>The element carbon is found in all organic substances. Carbon is also a primary constituent of <a href="https://kolektiva.social/tags/GreenhouseGases" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GreenhouseGases</span></a> that are responsible for <a href="https://kolektiva.social/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateChange</span></a>, such as carbon dioxide (CO2) and methane (<a href="https://kolektiva.social/tags/CH4" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CH4</span></a>). Carbon-14 (c-14) is a radioactive form of<br>carbon that occurs in nature and is also newly formed in nuclear power processes.<br> <br>"Carbon-14 is a health concern because it is released from <a href="https://kolektiva.social/tags/NuclearPower" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NuclearPower</span></a> facilities as radioactive carbon dioxide and methane, traveling readily in the local and global environment.</p><p>"Over time, carbon-14 becomes part of organic material including food, and has a half-life of approximately 5,730 years, decaying by a type of radioactive particle called a beta. Its hazardous life is 10-20 times its half-life, meaning that harmful exposure to man-made carbon-14 can last for hundreds of generations. The radioactive carbon forms as a byproduct of fissioning of uranium fuel, through a process called activation. The final step is a chemical reaction between carbon-14 and oxygen or hydrogen, which forms methane or carbon dioxide. The radioactive carbon-14 formed by this process is brand new and would not exist without nuclear fission.</p><p>"During its long hazardous life, carbon-14 could be responsible for gross physical or<br>mental defects, stillbirths and childhood deaths, embryonic and neonatal deaths into the many millions over the life of the isotope. </p><p>"These millions could be underestimated five times or more. Carbon-14 could also be responsible for <a href="https://kolektiva.social/tags/leukemia" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>leukemia</span></a>, bone and other <a href="https://kolektiva.social/tags/cancers" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cancers</span></a>."</p><p><a href="https://beyondnuclear.org/wp-content/uploads/2022/11/carbon14FINAL.pdf" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">beyondnuclear.org/wp-content/u</span><span class="invisible">ploads/2022/11/carbon14FINAL.pdf</span></a></p><p><a href="https://kolektiva.social/tags/NoNukes" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NoNukes</span></a> <a href="https://kolektiva.social/tags/RethinkNotRestart" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RethinkNotRestart</span></a> <a href="https://kolektiva.social/tags/NoNukesForAI" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NoNukesForAI</span></a> <a href="https://kolektiva.social/tags/RenewablesNow" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RenewablesNow</span></a>! <a href="https://kolektiva.social/tags/BeyondNuclear" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>BeyondNuclear</span></a> <a href="https://kolektiva.social/tags/NuclearIsNotCarbonFree" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NuclearIsNotCarbonFree</span></a></p>

Do you? Where did their information come from, and is it publicly available? </p><p>The energy carrier used in a power plant itself is necessarily the same as used for power generation, I guess. <br>But the energy for making the solvent and for transport and storage of the captured CO2 might be from a different source, potentially renewable. So that's why I'd like to have this split into two parts. </p><p>If a CCS+gas power plant needs, lets say, 3x more gas to actually remove CO2 from power generation compared to a gas power plant without CCS, </p><p>this CCS+gas incurs 3x more methane leakage! <br>AND also 3x more CO2. <br>So a test installation that allegedly removes 1Mt of CO2 per year, only removes 330kt from power generation, and the remaining 670kt removed were CO2 from the removal process itself? <br>Or in other words, 1Mt removed leads to 2Mt emitted?</p><p>I think, this information must be out there in the public debate. Especially now when the Green's newly legislated gas power plants of 12.5GW have been increased by the new government to 20 GW.</p><p>CCS means more gas is burned. The removal efficiency is bad. The methane leaks alone are making this endeavour even worse than just burning coal. <br> </p><p>Thank you for your help!</p><p><a href="https://climatejustice.social/tags/CCS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CCS</span></a> <a href="https://climatejustice.social/tags/CH4" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CH4</span></a> <a href="https://climatejustice.social/tags/CO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CO2</span></a> <a href="https://climatejustice.social/tags/FossilFuels" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FossilFuels</span></a> <a href="https://climatejustice.social/tags/climatechange" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>climatechange</span></a></p>
