In his presentation, he defined the latent period as being 1–5 years, and the formation coinciding with the period of maximum radiation dose. The recovery period was described as being 3–12 months after exposure ceased. He concluded that "CRS represents a systemic response of the body as a whole to the chronic total body exposure in man."
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
[41] [42] A chronic radiation keratosis is a precancerous keratotic skin lesion that may arise on the skin many years after exposure to ionizing radiation. [43]: 729 Various malignancies may develop, most frequency basal-cell carcinoma followed by squamous-cell carcinoma. [41] [44] [45] Elevated risk is confined to the site of radiation ...
The embryo and fetus are considered highly sensitive to radiation exposure. [8] Complications from radiation exposure include malformation of internal organs, reduction of IQ, and cancer formation. [8] The SI unit of exposure is the coulomb per kilogram (C/kg), which has largely replaced the roentgen (R). [9]
Diagnosis is typically made based on a history of significant radiation exposure and suitable clinical findings. [3] An absolute lymphocyte count can give a rough estimate of radiation exposure. [3] Time from exposure to vomiting can also give estimates of exposure levels if they are less than 10 Gy (1000 rad). [3]
Exposure to radiation causes chemical changes in gases. The least susceptible to damage are noble gases, where the major concern is the nuclear transmutation with follow-up chemical reactions of the nuclear reaction products. High-intensity ionizing radiation in air can produce a visible ionized air glow of telltale bluish-purplish color.
Exposing skin to infrared radiation near visible light (IR-A) leads to increased production of free radicals. [41] Short-term exposure can be beneficial (activating protective responses), while prolonged exposure can lead to photoaging. [42] Another important factor is the distance between the worker and the source of radiation.
Radiation burns should be covered by a clean, dry dressing as soon as possible to prevent infection. Wet dressings are not recommended. [48] The presence of combined injury (exposure to radiation plus trauma or radiation burn) increases the likelihood of generalized sepsis. [49] This requires administration of systemic antimicrobial therapy. [50]
