Teratogen is a substance that causes malformations for a foetus, when it's developing. Examples of teratogenes are alcohol, drugs, led etc.
teratogen
Exposure to high levels of ionizing radiation, such as from x-rays, nuclear fallout, or certain medical treatments, can be a teratogen that increases the risk of birth defects and developmental abnormalities in unborn babies. It is important for pregnant women to avoid unnecessary exposure to radiation and to follow safety protocols when undergoing medical procedures involving radiation.
Botulinum toxin is not classified as a mutagen, teratogen, or carcinogen. Its primary mechanism of action is through inhibition of nerve signaling, leading to muscle paralysis. It is used therapeutically in controlled doses, such as in Botox injections for cosmetic purposes or to treat certain medical conditions.
Each classification has his specific risk, also each substance.
I found your question while google-ing this question myself! The answer is:A teratogen is an exogenous substance that interferes with normal development of the foetus. A mutagen, on the other hand, directly affects and disrupts DNA by causing an increase in the rate of change in genes. These mutations can be passed along as the cell reproduces, sometimes leading to defective cells or cancer. Some agents, such as ionizing radiation, are teratogens and mutagens; ionizing radiation can cause defects either in development or it can damage DNA directly. Examples of mutagens include certain biological and chemical agents (cigarette smoke) as well exposure to ultraviolet light or ionizing radiation. Examples of teratogens include alcohol, rubella virus, cytomegalovirus and hyperthermia.So, a foetus that has developmental abnormalities due to a teratogenic substance has normal genes, but the development was disrupted and altered by the presence of the teratogen. A foetus that was exposed to a mutagenic substance has genetic abnormalities.
teratogen
No.
The level at which a teratogen becomes harmful is referred to as the teratogenic threshold. This threshold varies depending on the type of teratogen and the stage of development of the organism. Factors such as duration of exposure and genetic susceptibility can also influence the level at which a teratogen becomes harmful.

Teratogen
A teratogen is an agent or factor that causes malformation of an embryo. It would be likely to result in a spontaneous abortion, another name for a miscarriage or loss of the unborn child.
