For example, under the irradiation of 400rad [rad (radiation absorption)], 5% of the irradiated people died; If 650rad is irradiated, 100% of people die. Doses below 150 rad are associated with zero mortality, but they are not non-damaging, and it often takes 20 years for some symptoms to manifest. Radioactivity can also damage the dose-unit genetic material, mainly by causing genetic mutations and chromosomal aberrations, which can victimize one generation or even generations.
2.The main harm of formaldehyde is the irritation of the skin and mucous membranes, and when formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentrations greater than those can cause eye redness, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, wheezing, dermatitis, etc.
Newly renovated rooms have high levels of formaldehyde, which is a major cause of many diseases. In 2006, it was identified as a Group 1 carcinogen.
Therefore, no matter which exceeds the standard, it will cause harm to the human body.
